After seeing people comment on cutting themselves with their rotary cutter,I just bought a "Klutz Glove" ! I've given myself some slices,nothing serious,usually because I left the cutter open and slid up against it. But I've been alittle paranoid when I'm cutting since reading the comments..afraid the blade would jump over my ruler or something...so I took my 40% off coupon to Joanns and bought a glove!!!
