Tool Corner: Tool Tips

Share Button

By Roy Bloom, CJF APF-I

  1. Always wear your safety glasses. You are striking steel against steel and working with hot material. Anything can happen, so be safe.
  2. Always strike the tool in the center of the striking surface. Striking off center or on the edge will cause breakage and possible injury.
  3. Always strike the tool with the round face of your hammer. Striking with the flat face causes deflection off the rounded surface of the tool. The round face of your hammer produces a solid hit.
  4. Always pritchel at a black heat. This allows you to shear the material and avoid heat buildup in the pritchel. You will get much longer life from your pritchel and better nail holes.
  5. Always maintain your tools. If your tool should mushroom on the struck end, grind off the mushroomed area. If the working end should deform for any reason, regrind to the proper size and shape. Do not overheat.
  6. Never let the working end of your tool get too hot. Allowing your tools to remain in hot material too long will create a heat buildup in the working end of the tool that will destroy the heat treat and hardness of the tool. The result will be deformed working ends. This is especially critical with the forepunch and drift.
  7. Never put the tools in the fire to adjust. Excessive heat will destroy the heat treating and render the tool useless. Excessive heat will also destroy the weld on some tools and cause the weld to crack. (An exception would be tong adjustment and pritchels which can take some heat).
  8. Never quench your tools in water. If your tools get hot they should be allowed to air cool. In normal work we recommend that you dip your tools in a hoof packing formula to provide cooling and lubrication.
  9. Never quench your tongs in water. If you make adjustments to your tongs do not quench them. Allow them to air cool before you use them. In normal work, you can quench them in water provided there is no color in the tong.

Basic Shoeing: Foot Finish

Share Button

By Dave Farley

Your customers may never lift the foot to check your work but you can be sure they take a good look at the hoof as the horse is standing in front of them. A few minutes spent on a good finish will go a long way in keeping your customers happy.

We start our finish work when we pull the shoes. This work, as with most of the finish work, is done on the foot stand. This allows us to take a good look at the hoof and get some of the finish work done as a part of pulling the shoes. After cutting the clinches, we use the file side of the rasp to clean up the wall and begin to shape the hoof. We like to use the Bellota rasp which doesn’t have a real coarse file side.

On foot stand, use file side to begin clean up.

One thing we want to avoid are deep marks in the wall. Doing this work now also keeps us from having to worry about rasping around the clinches (or clips) after nailing the shoes on.

At this point we pull the shoes, using a crease nail puller to avoid any wall damage. After pulling the shoes be sure to clean the wall all the way to the end of the heels. It’s sometimes difficult to get to this area when the shoe is on.

 

After nailing, we bring the foot back to the stand and use the undercut before clinching to avoid marking the wall. Once we’ve clinched we lightly file the foot if needed. By using the undercut we can often bypass this step and go right to the sanding block. A good run with the sanding block should remove any file marks.

Our final step is to apply a sealant like the Diamond Hoof Defender. This can help with maintenance of the hoof. It only takes a minute and the customers appreciate the extra touch. Remember what they see when you’re finished.

What is it Like Shoeing a Million Dollar Horse?

Share Button

Guest Blog by Rob Logsdon, FPD, Inc.

Lexington, Kentucky is largely considered the “Horse Capital of the World” because of the numerous horse farms, Keeneland Racecourse and Keeneland Association Thoroughbred Auctions. From September 10 to 23, Keeneland is hosting their September Yearling Sale, recognized as the top horse sale in the world. To date, the 2018 September Yearling Sale has sold 26 horses for $1,000,000 or more. The 2018 sale topper was a $2.4 million yearling shod by Brandon Coats, CJF for Hill ‘n’ Dale Sales Agency.

Sale yearlings awaiting Kerckhaert DR 15×7 shoes.

Brandon Coats, CJF fitting Kerckhaert Kings Plate.

I recently visited with Brandon and farrier Mick Maynard while they were working at Stonereath Stud. The yearlings they were shoeing with various Kerckhaert horseshoes (DR 15×7 and Kings Aluminum) are to be sold this weekend at the Keeneland sales. Brandon explained that the majority of his work is for breeding farms, specific to selling horses and that he typically begins when the yearlings are babies. The farrier is the first line of defense in regards to a horse’s conformation and for the first two months these babies are evaluated and trimmed every 8 to 14 days. After two months the farm manager, farrier and vet review the farrier’s notes and devise a plan for the horse.

When a horse is a yearling, their trimming schedule typically is extended to every three weeks until they are sold. The ultimate goal is to sell these yearlings for the highest price possible. There is a saying in Lexington, “breed the best to the best and hope for the best.” There is a lot of work, time and luck involved with these million-dollar babies. The farrier is instrumental and invaluable for these horses to reach their full potential in the sales arena.

Most of the yearlings sold are fitted with the Kerckhaert DR 15×7 steel shoes. The shape, fit and nail punching make this the preferred horseshoe for sale yearlings. The Kerckhaert Kings Plate Aluminum will be used if the yearling needs a lighter and wider web horseshoe.

Basic Shoeing: 12 Points of Reference for Evaluating Limb Balance

Share Button

By Dave Farley and Roy Bloom

We have developed a list of reference points that have helped us in evaluating limb balance and developing a plan for trimming the hoof to maintain or enhance the balance. The following list and images give a good overview of those points and will hopefully give you food for thought in your daily work.

 

 

10. From the same farrier’s position (FP) find the medial/lateral center of the frog (approximately 3/8” back from the point of the frog). Measure from that point to the widest part of the quarters, both medial and lateral and compare measurements.

 

12a. With hoof on the foot stand, sight over the coronary band to compare the shape of the hoof edge to the coronary band’s shape. A contour gauge can be very helpful in comparing coronary band shape to the toe.

12b. With hoof on the foot stand, sight over the coronary band to compare the shape of the hoof edge to the coronary band’s shape. A contour gauge can be very helpful in comparing coronary band shape to the toe.

The challenge you face in establishing good hoof and limb balance is lessened when you develop your overall perspective of the limb. These reference points are a good guide to help with that effort. It’s nearly impossible to accomplish your goal of achieving good balance when looking only at the hoof when in working position. We’ve found these points of reference to be invaluable in our everyday work. We look forward to going into more detail on the variations we see in these reference points in the video series and future articles.

Setting Standards for Hoof Preparation

Share Button

by Bobby Menker, CJF APF

One of the best ways to prepare for the practical portion of the AFA certification test is to study the guidelines set forth in the AFA pamphlet “Guidelines for Evaluating Farrier Competitions and Certifications” and incorporate them into your everyday shoeing.

 

The accompanying photographs outline proper hoof prep as desired for certification as well as illustrating some of the common errors seen by examiners. It is important to note that all hoof prep must be completed and will be judged before you can proceed to the next step of nailing on the shoe.

The benefits of integrating these guidelines into your daily shoeing are twofold. Not only will you gain experience that will help you formulate your game plan for test day, but the principles outlined in the guide result in a nice, solid shoeing, definitely an asset to your business.



Photos 1, 2 and 3: It has been 7 weeks since the last shoeing. The foot runs forward and carries a medial toe flare.

Photo 4: Clean bulb and heel area. Start to establish the widest portion of the frog using the angle of the heel.

Photo 5: Paring the frog, keep it neat and smooth. Keeping the knife straight up allows you to establish a solid frog

Photo 6: Prep the sole. You want it to be smooth and not weakened by over-paring. Bars should be solid and the sole should not give to thumb
pressure.

Photo 11:

Photo 11: Check for a flat surface.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Photo 14:

Photo 14: Sand block the wall and the back of the heel area to smooth everything. This helps to give a nice finished appearance.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Photos 15 & 16: These show the finished job. The wall is smooth and straight with no deep rasp marks or gouges. The edges are smooth and rounded so that there is no injury to yourself, the horse or the examiner. The toe is not dubbed and the dishes and flares have been dressed without endangering the nailing job.

Photo 17:

Photo 17: Lateral view, resetting the same shoes. Shows how much improvement was made through good hoof prep.

 

 

 

 

 

 

 

 

 

 

 

 

The mistakes shown in photos 19-24 would result in scores less than 6.

Photo 20:

Photo 20: The foot has been trimmed out of balance. The bulb area has been left untouched.

 

 

 

 

 

 

 

Photo 21

Photo 21: The bottom of the foot is not level. There is a gap in the toe and quarter area.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Photo 22 & 23: The dish in the toe hasn’t been dressed. Deep rasp marks are left in the wall. The heel area hasn’t been touched and the edge is not smooth.

Photo 24: You will be stopped for drawing blood, unless an AFA examiner feels that it could not be helped.

A Working Knowledge of Anatomy is ­Important to Everyday Shoeing Concerns

Share Button

By Mitch Taylor

In order to gain a better understanding of how to approach a variety of situations in foot care, a working knowledge of the parts of the foot and leg and how they relate or ‘communicate’ with each other is necessary.

This sketch illustrates the differences of bone contact to the ground between a horse and human foot. Notice the horse’s coffin bone is suspended while the human’s foot has direct ground contact.

In nature, the general rule is that form follows function. Therefore, if you understand how a particular structure or system works, it is much easier to remember its parts. The names and types of bones in horse limbs are almost exactly the same as ours. So, if you know anything of your own anatomy, it’s much easier to remember horse anatomy. For example, both the human and the horse have a scapula, humerus, radius, ulna, carpal bones, metacarpal bones and three bones called phalanges that make up our digits. However, the functions of our arms and those of the horse’s forelimb are completely different making the arrangement and lengths of bone, and number of digits more suited to the needs of each animal.

One of the main differences between our feet and horses’ feet is that our feet are much bigger in proportion to our body weight than the horse. Our feet don’t deal with anywhere near the concussion that a horse does. If you look at the form of our feet, the bones are in almost direct contact with the ground, protected only by skin (sometimes callused) and small fibro-fat pads, which allow for easy bruising of the underlying bones when barefooted. Conversely, if we consider the horse’s foot, its form is designed to withstand tremendous forces. Basically, the bones of the horse’s foot (the coffin and navicular bones) are protected from direct contact with the ground by being suspended within the hoof capsule via the laminar bed.

The horse is unique in that it is able to travel great distances at moderate speeds and relatively short distances at high rates of speed. Few other animals have specialized their
locomotor systems to incorporate both of these characteristics. By design, the feet and legs of horses must be able not only to bear the animal’s full weight but dissipate enormous amounts of shock generated as the foot hits the ground at high rates of speed in order to maintain soundness. In addition to weight bearing and shock absorption, the foot must provide some natural traction and serve as a venous blood pump to clear the blood from the foot on its way back up the leg.

Let’s look at it another way. When the average size horse (1000 lbs.) is breezing along at 30 mph the concussion that each foot and leg must deal with per stride is approximately 10,000 lbs. How does the very porous 2 1/2-ounce coffin bone handle this violent impact with the ground without fracturing?

Because the foot is the first thing to receive the impact of the ground at speed it is the first line of defense in dissipating that energy. In order to accomplish this, the foot must be both strong and elastic. Much like an engineer will combine the strengths of steel and concrete to build a foundation that not only can handle incredible weight, but also will have some ability to yield to changing conditions, the horse has developed a highly specialized form in its leg and foot that utilizes several different types of “materials” or tissues that when combined together are stronger than any of them alone. The design of the foot utilizes bone because it is best suited to resist compression. The coffin bone being porous would at first glance seem very fragile. But, when this bone is engorged with blood it is as strong as very dense bone and can have some elasticity if needed during the peak loading times of the stride. The navicular bone is situated adjacent to and just to the rear of the coffin bone within the hoof capsule. Two strong ligaments, the suspensory ligament of the navicular bone and the impar or distal navicular ligament hold it in place. It makes up about 1/3 of the floor of the coffin joint. The short pastern bone rests on the coffin bone and the navicular bone. Because the navicular bone is a separate entity and held in place by ‘elastic’ ligaments, the rear 1/3 of the coffin joint can ‘hinge’ or move to dissipate some energy as the pastern drops.

The hoof capsule can be described as those insensitive, protective, weight bearing structures of the foot consisting of the hoof wall, white line, sole, frog, bars and bulbs. The hoof wall takes the general shape of a cone with the top cut off. Foundations are strongest when the base is wider than the top. The function of the wall is to bear weight. It is a constant weight bearing structure, i.e., it will bear weight on hard ground or soft, bare footed or shod. Weight is transferred from the wall through the laminar bed to the bony column of the leg. The wall is designed to temporarily distort under a load. Most of the distortion of the normal foot is measured in the heel area as the heels expand.

The sole is an intermittent weight bearing structure i.e.; it bears weight depending on the situation. Obviously, if the foot is not shod and is on soft terrain the sole will contact the ground and bear weight. Only after the wall has taken a considerable amount of the load first though. A healthy dense sole is designed to handle this. If, however, the foot is shod and on hard ground it may not contact the ground at all. But because the sole is the protective foundation of the bottom of the coffin bone, it will take some weight from above. The sole is concave. It is concave because the bottom of the coffin bone from which it grows from is concave. This concave form is no accident. It functions like a leaf spring from a car, which flattens when loaded (due to the weight of the horse from above and the outward distortion of the wall) and returns to its original shape when unloaded. When soles are over pared one not only exposes the underlying sensitive sole to bruising and potential changes of the coffin bone but also, weaken this natural ‘dome’ and the ability of the sole to rebound back to its original shape. This results in flatter soles. Flatter soles result in less upright walls that are not as strong.

The white line joins the sole to the wall. It can be likened to the rubber caulking between two cement pads at a pool. It is an elastic bond between the sole and wall that allows for some movement. The white line does not run from the ground to the coronary band but is only as thick as the insensitive sole. The white line begins at the junction of the sensitive laminae and sensitive sole. It is a constant weight bearing structure.

The normal healthy frog will take up about 1/3 of the bottom surface of the hoof. It is an intermittently weight bearing structure. It has a triangular shape with the base of the triangle being even with the buttress of the heels of the foot. The frog is an important component of the natural traction capabilities of the foot. The triangular form furrows into soft ground, much the same as a plowshare does, helping the foot stop. The soft fleshy feel of the frog helps the foot to grip hard ground as the horse turns and sets up to breakover. The frog originates from its sensitive counterpart, the sensitive frog, and is connected to the hoof capsule by way of the commisure. When viewing the foot from behind the frog has the shape of a W. This form facilitates the expansion and contraction of the heel area under the strain of a load without sacrificing strength.

The bars are sometimes a forgotten structure of the foot. They are formed as the wall folds in on itself at the buttress of the heel. Commonly over pared, they are crucial for hoof strength. Think of the bars as internal struts of the capsule. Much like the cross members on the legs of a fold up table help it to be more stable, the bars help increase the foot’s stability.

Up to this point we have only really talked about the insensitive hoof capsule and its bones. It is important to remember the inner sensitive structures as well. These structures comprise vasculature, fibrous cushions, interlocking laminae and cartilage. The health of these underlying tissues is dependent on the structural integrity of the hoof capsule and its ability to hold up under less than desirable conditions. Therefore, as stewards of the feet we must know anatomy, respect the horn that constitutes the hoof capsule and employ sound farrier principals to promote healthy growth of the foot.

Basic Shoeing: What Kind of View Do You Have?

Share Button

by Dave Farley, CF APF-I

One of the steps to getting a good trim is often overlooked. If you don’t have a good view of the balance of the bottom of the foot it is difficult to get the best trim. How you hold the leg affects the view of the foot, sometimes dramatically changing the perception you end up with.

Many farriers have found that holding the leg in its most natural position is the best way to get a true picture of the balance. This applies to front or hind. Take a look at the pictures. Try holding the leg in the various positions. You may be surprised at the differences in what you might have done with the foot trim based on how you see the hoof in these positions.

 

 

If you hold the front foot similar to photos 1 and 2 you are very likely getting a distorted view. Your hand, especially the thumb pressure, will push the hoof capsule in one direction or another.

Holding the leg out from the body, as in photos 3, 4, and 5 will also create a distorted view.

Try holding the leg by the cannon bone and staying in line with the body. The hoof may be under the horse and you will have to crouch to get the view but it gives you the most accurate view of how the hoof aligns with the cannon bone and gives you a much better starting point for your trim. See photos 6, 7 and 8.

Photo 9

The hind view is similarly affected by not allowing the limb to hang as freely and near its natural position as possible. Pushing the leg out of position with your inside knee will make it difficult to see the true alignment of the hoof capsule to the leg. This is evident in photo 9.

Hold the leg under the hock joint and keep the cannon bone perpendicular to the ground as it is shown in photos 10 & 11.

If the cannon bone is pulled forward or pushed back as it is in photos 12 & 13 it will distort your view – particularly of the toe and heel length.

Your trim should always be done with the alignment of the hoof capsule to the leg in mind. Hopefully these tips will help you to improve the view and the trim.

Basic Shoeing: Working with a Chronic Quarter Crack

Share Button

by Dave Farley, CF APF-I

These are pictures of a chronic quarter crack that reopened (Image 1).

 

All farriers get this type of call and the question, “Can you do something with this? I have a show in a few days so he can’t have any time off.”

 

Image 2

Image 1

 

First it is important to get the history. This horse was purchased two years ago with a crack in the same spot. The horse was never lame. Now, two years later, another one pops.

Looking at this horse (Image 2) it is easy to see there are conformation faults that led to the crack. The foot is typical as it lands on the outside then slams the inside as the horse’s weight passes over it. The medial wall is forced higher and higher causing it to shear. The wall will shear and stress until it cracks.

This is how I handled this one. First we took a good look at the foot (Images 3, 4, 5) before pulling the shoe. Notice the location of the crack at the coronary. The heel is sheared. The foot needs to be balanced. Notice that the crack is open at the coronary band. It needs to be dremeled out and soaked a few days before patching.

Image 6

Now we pull the shoe (Image 6) and balance the foot. Once the foot is trimmed we float the area under the crack as well as the sheared heel. It is important to unload the sheared heel, as this entire area perpendicular to the ground needs to be non-weight bearing before the heel can settle and the crack can heal at the coronary. Even though we float the heel and unload the sheared heel (Image 7) it will take a long time, if ever, for this area to go back to normal.

I prefer a flex shaft dremel (Image 8) as the long shaft allows me to keep the motor away from the horse. Also the working end of the flex shaft is much lighter and easier to control. I use a 1/8″ dremel burr. If you have never opened a quarter crack before I recommend that you attend a hands on clinic on dissection.

Image 8

Image 7

The hoof is a vital living part of the horse and you should not attempt this without some education.

At least practice on a tangerine or a tangelo. Practice taking the skin off without cutting into the pulp. When you can achieve this use an apple. When you can take off only the skin you have control of the dremel. The wall thickness at the coronary is paper-thin. When using the dremel hold it with both hands and put your hands against the hoof. If the horse should move, and they do, your hand will be pushed away instead of the dremel going into the hoof.

Remember that you are only a credit card thickness away from sensitive structures so be careful. I also keep a new or sharp burr in the dremel. If it gets dull or rusty it generates too much heat.

Image 12

Start at the coronary where the wall is the thinnest (Images 9, 10, 11) and move the dremel down following the crack. Keep the burr moving, as heat will build up if left in one place too long. Open the crack completely and be very careful not to get too deep. On this foot the area behind the crack had been undermined and we remove all the weak wall structure. After the entire area is open advise the client to soak twice a day for at least three days, more if the crack is bleeding or infected. After that time has passed and the foot is dry (Image 12) you can patch it with the product of your choice. I use Vettec Adhere.

It is easy to apply, stays in place and sets quick without too much heat. You should always ask the owner to have their vet look at the case before you do your work. Discuss the situation with the vet whenever possible so everyone is on the same page with the treatment. It can also be helpful to have the horse tranquilized before beginning the dremel work. If you have a camera, take before and after pictures for your records.

Basic Shoeing: Guidelines for Balance

Share Button

By Bob Pethick, CJF APF

Farriers should not be trying to straighten limbs in aged horses. You’re simply trying to make the horse comfortable for it’s conformation. To help a horse become comfortable, you need to limit hoof distortion by trimming the hoof to bear weight as evenly as possible. A farrier’s key to hoof balance is being able to recognize the cause and effect of distortion. If uneven growth is allowed to continue unchecked, the hoof capsule distortion could cause a breakdown of hoof integrity and eventually lameness in the limb. Uneven hoof growth due to conformation problems will compound those problems.

When farriers are dealing with a client whose horse has a balance problem, references that the farrier may cite may not be up-to-date. This problem may also occur when working with veterinarians. The farrier needs to be up-to-date on the current research and theories to be able to explain why the problem exists in the first place.

As farriers, we are working from the coronary band down. What happens above the coronary band can be seen in the distortion of the hoof capsule. My philosophy is if you can balance the hoof according to weight bearing, the horse will land and move the best it can for its conformation. I recommend using Russell’s “center of gravity” as a point of reference for solving hoof distortion problems. More precisely, using the center of the frog because the frog never really moves, the hoof capsule distorts around it.

A major influence on hoof angle is tendon tension. The amount of tension will change how the hoof loads. If you have an upright foot, chances are the deep flexor tendon will be tight which will limit the amount of load on the heels by transferring weight bearing to the toe, limiting toe and increasing heel growth. If you have a horse with a low hoof angle and under run heels, there will be less tension on the deep flexor tendon, increasing weight, limiting growth and crushing the heels.

For the hoof capsule to function normally, it is important to make sure that the hoof is trimmed to its proper proportions and kept symmetrical both medial/lateral and anterior/posterior. When you are limited with what you can accomplish with trimming, the fit of the shoe can complete the equation by providing a base of support or platform for the limb above it.

Anterior/Posterior: The hoof capsule interprets weight bearing and load in two ways. It either loads forward of the centerline or back of the centerline and tendon and suspensory tension allows the fetlock to drop what we consider normally, excessively, or very little. All of the above effect growth of the heels and toe. The least amount of growth will occur where the majority of the weight is applied. The hoof will grow at a faster rate where the least amount of weight is applied, causing an imbalance which is compounded over time. When you add torque at breakover it becomes more obvious why long toe low heel syndrome is as detrimental to soundness as it is.

Medial/Lateral: The hoof capsule also interprets weight bearing and load in two ways. It will be either base-wide, loading outside the centerline or base-narrow, loading inside the centerline. The effects of base loading are seen from the widest part of the hoof back in the heel quarters. The quarter bearing the most weight will have the least amount of growth, become more vertical, closer to the frog and in extreme cases, considered a sheared heel. The quarter bearing the least amount of weight will grow at a faster rate away from the center of the hoof, causing an imbalance compounded over time. Base-wide will effect the medial heel quarter. Base-narrow will effect the lateral heel quarter.

The second consideration is toe-in, toe-out conformation. This effects the hoof from the widest part of the foot forward or the toe quarters. The quarter bearing the most weight at breakover will have limited growth while the opposite toe quarter will grow at a normal or a faster rate becoming a flair. Toe-in will have a flair on the medial toe quarter. Toe-out will have a flair on the lateral toe quarter.

All distortion in the hoof capsule is a combination of weight bearing, compression, load and torque and is directly related to the conformation of the limb above it. Remember, whenever horses are standing on their feet these forces are at work effecting growth.

Once we have an understanding of why hoof capsules distort, only then can we actually start to “balance” horses.

Tool Corner: Simple Steps Lead to Consistent Clinching

Share Button

Two methods of clinching are the hammer clinch and the use of a clinching tool. Both methods have the same goal – to provide a neat, safe and effective clinch.

In recent years, many farriers have come to rely almost completely on the clincher in their finish work. The following ideas and pictures illustrate some of the steps that can be used in this method. No matter what method you use, your clinches should be of consistent length and smooth when completed. Long clinches add no strength to the job.

Unless you are in an old nail hole you will always get a bit of hoof pushed out under the nail. It is most obvious after you have blocked the nails and are getting ready to do the clinching. If you are careful with the smooth side of your rasp or finish file you can clean this up by running the file or rasp under the nail. If you don’t take care with this method you can leave unsightly lines between the nails. Some believe these lines, which are often parallel to the ground, create a weakness in the wall, something like cutting glass. It is also very difficult to create a “bed” to set the clinch in using this method.

These photos show that the nails have been blocked:

To avoid the possibility of weakening the wall or leaving unsightly marks you can use the undercut method.

Start by using the clincher to pull the nail to a 90 degree angle to the wall. Then cut the nail very close to the wall. You want to leave only enough nail to be able to grab it with your clincher.

After cutting the nail, use the undercut to cut a scoop or create a bed for the clinch to go in. This allows your clinch to be squeezed tight against the hoof without leaving nail on the outer surface to be filed off. In the end you have more nail mass at the bend of the clinch, providing a much stronger clinch and a flush fit with the wall.

These photos illustrate the above steps:

When clinching, don’t yank downward in a raking motion. This can tear more hoof below the clinch if the motion is too strong and at the very least leave unsightly marks. You should be able to squeeze the clinchers with a very light motion and bend the clinch over. This squeezing pushes the clinch back into the bed you have created. You might even find that a slight upward motion of your tool, while squeezing, produces a neater clinch, and job, than if you rake downward.

Finished job with clinches lightly filed and sand blocked.

There are a number of clinchers available. The traditional saddle horse clincher is the most commonly used. Other styles on the market include curved jaw versions and styles with an angled head that make it easier to position your hands to make the squeeze to do the clinch.
