Abstract: A farrier's tool and a method of using the tool for preparing the hoof of a horse to receive a shoe. The tool is a symmetrical measuring device used for determining the position of the breakover point on a horse's hoof. After the position of the break-over point is determined, the portion of the hoofwall forward of the breakover point is beveled by means of a trimming tool to reduce leverage on the underlying coffin bone, particularly during locomotion. A horseshoe is then shaped to conform to the contour of the trimmed and beveled hoof and nailed to the hoof. The method provides means for accurately aligning the hoof capsule with the coffin bone in the hoof.
