How is the Shoe Punched?
The Diamond Difference

This is one of the most common questions asked about horseshoes. The target for most manufacturers of riding horseshoes made for the North American market is to crease and punch for a city head nail, normally the 5 City. The V-shaped crease of the Diamond horseshoe allows a countersink which maximizes contact with the nail head.  If you were to measure the amount of surface area of the nail (head and shank) making good contact with the Diamond shoe you would see that more head contact is possible.  This proves stronger than having contact only with the base of the head and the top of the nail shank.  The V-crease with the countersink for the head facilitates nail head contact with the shoe, lessening the dependency on the pritcheling to be so tight.  This allows the nail to be angled or pitched to suit the hoof angle.  

The result is a secure shoe with a minimum amount of hoof wall damage.  With a V-creased shoe a farrier is able to use slimmer shank nails with good results. There is also much less effort involved in shoe preparation - less backpunching!

Ask a nail manufacturer what design feature they think will do the most to hold a shoe on. They will probably indicate good head fit with a maximum amount of contact with the crease. In summary, the improved Diamond horseshoes feature a deeper crease with an adjusted nail pitch, angled more favorably to the shape of the hoof.  With less work involved for the farrier - and a more secure nail fit - Diamond horseshoes provide a better end result for farriers and the horse than competitor brand shoes.
