ok, this is how it happened. i do not have any tongs yet, nor steel to make them. i was using vise grips to hold the 1 inch bolt that i was using. getting tongs very very soon! i hit it with a normal strike and it jumped out of the vise grips, and went sailing through the air to make an extremely brief contact with my forearm and wrist, continued sailing till it landed on the floor. the floor started snapping and cracking, i thought this to be rather comical. and i didn't feel it much till my grandma said that there was an entire layer missing. i know never ever grab for a falling or fallen object that is a lesson that i need not learn. thanks for the advice and sharing stories
