This structure makes the rasp well suited for softer, damper horn material that tends to clog a finely toothed rasp. This rasp is particularly good for sport horses that are shod. The file side of the Heller rasps is sharp, enabling efficient removal of material with little effort. The Heller Legend is a rasp with a larger tooth angle, resulting in a more open structure in the rasp. For horses that spend much of their time outside in the sand and mud, the Black Legend is probably a better choice.
