I never had A huge gaffing accident when I was first learning I gaffed out and the spike slide down my shine. That was about it. I do the twinkle toes when I go from the truck to the tree at first but If I have been on them all day I start doing the john Wayne impression.
Most of my climbs are gaff climbs, and I am sorry to say sometimes when I came down I do drag brush in them. Yesterday I caught my gaff in my chapps but I think that was just crappy set of chaps more then the gaff.
I dont know if there should be regs, Just because the same accedents we are truely worried about can happen in the tree. I seen people Gaff their toes, feet, calf, hands, I even seen a guy get it in the top of the knee, all in a tree.
But I could see were they would be useful walking over a wood pile when its raining, maybee I wouldn't have cut my toes with a saw if I had them on. /forum/images/graemlins/damnmate.gif
