Reading the posts, I have to think that most folks trying to trim have dull tools. It makes a huge difference. A rasp, nippers or hoof knife is not supposed to last months and YEARS!! Especially if YOU don’t sharpen them often or replace the rasp. They gouge you precisely because they ARE SHARP!! Sharp actually means you work easier, with less effort, can go faster in gaining desired results!
I trimmed and shod horses part time for about 10 years after going to horseshoeing school. Met husband the full time Farrier at the Michigan Horseshoers yearly Jan clinic. I learned that being “cheap” in trying to use cheap, dull tools, worn rasp was way more work than the job needed. Husband said if he had to push down on a rasp, it was dull. Weight of the rasp should be enough to smooth the edges. We both used nippers, but upgrading to GE nippers was eye opening!! Like a hot knife thru butter, soft or hard hooves made no difference. If the GEs were having cutting problems, they needed to be sent back to GE for resharpening. He carried a couple pairs on the truck, in case pair 1 suddenly was not cutting well.
We never used the grinder tools, saw horses trying to recover from burned hooves after the previous trimmer got hooves too hot, burned them. Sad to say some did not recover from that.
I went on to take a regular daily job with benefits! Quit shoeing. Husband stayed a full-time Farrier until he retired. I just kept getting him repaired! Ha ha The daily morning routine was stocking his truck, sharpening several hoof knives from use the day before. He used the grinder, cloth wheel and a polishing paste to sharpen them. You could shave with them! Most days he got out a new rasp to use. They were usually dulled enough from the previous day that he could tell the difference, wanted a new, sharper rasp for the new day. Said he didn’t have to work as hard with a new rasp!
Daughter went into Farrier work, attended school and worked under her Dad apprenticing. He is a hard boss! But she says the same thing about using sharp tools, easier on you than fighting with dull tools! You can do a more precise job in a much shorter time. Get tools that fit YOU. She has smaller hands, uses appropriately sized GE nippers, tongs, reshapes hoof knife handles for her hands. Diamond farrier tools found at TSC and farm stores are too heavy for small hands, overlong handles, will NOT hold a sharp edge very long. Rasps dull up fast. I resell husband’s “old” rasps at tack sales for reduced prices. They are still plenty sharp for home trimmers to hurt themselves on! Ha ha
If you really want to get into trimming your own equines, use SHARP tools.
