Why would you want a Farrier rasp? What is a Farrier anyway?
Well, a farrier takes care of trimming and shoeing horses’ hooves.
They use a very large rasp about 14″ long and 1 3/4″ wide that has a very coarse side and a finer side.

Amazingly, these files only last a few days of rasping hooves before they are too dull, and require too many passes to flatten a hoof. Farriers typically throw them away or give away to someone who makes knives.
However, once they are too dull for farrier use they make GREAT rasps for shaping guitar or lute necks. They are also handy for jobs you would not expect because they look so aggressive. Their length and great width are handy for flattening at odd times as well.
I collect these rasps from time to time because we also have a horse and cattle ranch and am offering them to luthiers if you are interested. I clean them up, so if you want to give one a try, just let me know. You can buy new of course, for $25 or so, but they really ARE too sharp when new. I can send you a used one for $20 plus shipping.
