Are you kidding? I'd like to meet someone who uses a rotary cutter and HASN'T cut her finger! Don't feel dumb, just use one of the handy tools, gloves, etc., that will prevent the next one. I even cut my finger bad once by reaching into the pocket of my carrier and had not locked the rotary cutter when I put it in the pocket! My teen-age grandson wnted to "help" me cut one time, and all the warnings were ignored! Bet he will listen next time!
