The rasp
The manufacture of files and rasps goes back centuries. Drawings for machines to produce files are found going back as far as the time of Leonardo da Vinci. Rasps and files are important for both the metalworking and woodworking industries. For the farrier, a good rasp is one that is sharp and predictably removes material without the teeth becoming clogged, regardless of the direction of work.
In principle, for a farrier, a single rasp should be sufficient for every horse, although hoof horn quality can vary greatly among horses based on hereditary and environmental factors. It is essential that both softer horns as well as those that are rock hard can be quickly, easily and properly rasped and filed.
