Well, I can attest that my cheap rasps purchased at a local chain get dull really, really quickly, as do the knives. If I knew how to sharpen the knives well that would be one thing, but my only attempt was a horrid failure. With this mind I will continue to nuy cheap knives until I learn how to properly sharpen one, but I am definitely going to purchase a good rasp and a Hoofjack stand. I had a Hoofjack years ago when I first thought I would learn to trim, but gave it away when I knew I wasn't ready. That was a mistake and now I need it more than ever as my back starts giving out on me.
Non-trim tools I find invaluable are a pointy pick with a brush on it, a small, stiff plastic brush for scrubbing feet clean, and a small, brass wire brush (head is about an inch by half inch) for scrubbing out collateral grooves and, on my horse, places where were were dealing with some separation due to flaring.
