Pritchel
A pritchel is a type of punch used in forging, particularly in making nail holes in horseshoes. The horseshoe is heated and a hole is punched through 90 percent of the steel with a forepunch or drift punch. The pointed end of the tool should be kept sharp and so that the burr is cut out smoothly. The punched hole is lined up over the pritchel hole and the pritchel is driven into the hole, knocking out the remaining metal at the bottom of the punched hole.
The temperature of the pritchel should be always below the ''red-hot'' stage as the tool itself will bend and lose the temper. When over-heated it is advised to cool it in water intermediately.〔
==Back pritcheling==
The pritchel should normally be driven from the bottom of the shoe, similarly as the nail is driven. ''Back pritcheling'' is the process of driving it from the opposite side —the hoof side— leaving burrs and resulting in the weakening and cutting the nails.
