I’ve been doing mine for the last… 4 years? After trying the only “barefoot” trimmer in my area, who I promptly fired mid-trim for being a jerk. Chocomare helped me get started, and I read, watch, and study religiously to this day.
Good tools make a difference. I just got a new shipment in yesterday, and I waited way too long to get a new rasp I really like my Heller Blackmaster, but it is aggressive. I always wear gloves because even after 4 years I still try to shave off the occasional knuckle.
I agree with all the educational recommendations. Less is more at first, if you don’t have supervision. Don’t be afraid to just do a little at a time - you’re not a farrier on a schedule, you don’t need to get all 12 feet done in one day (or even all 4 on one horse). Try to avoid trimming guides/techniques that seem overly drastic, making horses sore or bleeding is not normal.
Sometimes it seems like a lot of work, and it is, but it is also extremely rewarding and liberating. At least that’s what I tell myself on days like today when the 2yo accidentally stomped on my toe.
