I actually wore my chainmail to work when I worked for Iowa Metal Spinners. I worked as a disc cutter for a while and you put a square of sheet metal on a spinner dealie and you engage a cutter which cuts it out. Only problem is, if you get to close, cuts your belly right open. Several guys that worked there had scars from serious cuts, but I never got one thanks to the chainmail, and it did indeed work when one day I got bumped right into the path of the corners by another worker.
