Good to see other horseshoers around. Personaly for hoof knives I dont think I would try a rasp. I made a pretty sweet hunting knife for my brother last year out of a rasp. I have seen shoes and such made with them and I have seen some people use them to forge weld in as the bar on a straight bar shoe. The snakes are cool and that dragon above is AWESOME! Spurs look great when made with rasp. I also have a clinch block I made from a finishing rasp. You could make a clinch cutter or a hoof gouge if you use either of them. I have seen people stick them in the ground tang down around flower beds and such.
