Yeah but if I were to be say driving down the road an ol Officer friendly pulls me over,my ol #33 is in a bag with cleats,socks,and a ball& glove,now Im gonna look pretty GUILTY with the nail thing. The other benefit of wood is that if it became say,tainted,with an incriminating substance,like oh ....just suppose,blood,teeth or maybe brain matter,wood will burn,metal? Not so much.
