Do you hit your throw hand or your free hand more often. Noticed recently I hit my freehand most often by far. I play 5a mostly so it is my dice hitting me normally.
Same. Freehand
I almost never hit my non-throwhand.
My dam elbow. Every time. Sounds like a drum.
Usually my non throw hand, be it on a strong throw with an unexpected snag (safety throw first, guys!) or having a snag in the middle of a trick.
Stainless steel rims seem to hurt more than my aluminum throws, and I have shaved off a thin layer of skin 
Usually my non throw hand
I seem to hit both equally. Depends on the trick really. Either way my knuckles take a regular beating. 
Interesting. seems to be around 50/50
what if i have three arms?

Freehand. It doesn’t happen as much as it used to. I dinged alot of yoyos early on by hitting my wedding ring.
Sadly, I lost track at 50 each.
I play 1a mostly, and really only hit my throwhand. I’m trying to get into 4a and 5a, but I still suck at those.
With 5A, it tends to be my NTH; but in 1A, it’s definitely my TH based on poorly executed binds and the like.
I’m with Gambit here. I usually hit my throw hand when I get snag which causes quite often sometimes, and of course my throwhand when I fail at string hits :\
