When I first started doing it I actually considered getting an archers style wrist guard. Always had these little sliced from slipping with the knives. Still 4 or 5 little scars on my wrists and I haven't (knock on wood) slipped in many years.
Got one good on on my forearm because I was stupid and tried to hang on to a horse that wanted a break. Immediately drove myself to the hospital for a tetanus booster. That was a hassle. Tried my doctor and my pediatrician first and they said they had none. So I sat in the ER for 3 hours with a nurse who kept telling me I needed to put the hospital johnny on. Finally told her it was my arm and not my butt. Had a bored toddler in tow. Then listen to doctor who wanted to prescribe all kinds of antibiotics and give a couple of stitches. Finally had to get a little snarly to just get the shot.
I had a cheap pair of leather gloves that worked pretty good. I admit I'm bad about wearing gloves. I do remember skinning my hands up pretty good in the beginning.
