I find that once I don my safety gear, I can concentrate on the task at hand, without having to look sideways at a saw spitting out chunks of material... I have mentioned here before, that I get a lot of comfort from a leather shop apron, simply because I don't care what hits it.. simple chips or saw-dust..all fine by me, and I know that a stray router-bit (and my work is very router dependant, some bits quite large) won't cut me. It also keeps belt-buckles, cell-phone pouch out of the way.. and my pockets don't fill with chaff. I have converted a few fellow butchers to wearing them, and they couldn't imagine walking into their shop without an apron now.
