Nina, sorry to hear about your injury! I hope all is well in a few days. I just purchased a new rotary cutter yesterday. Can you believe I broke one? The plastic slide thingy that retracts the blade broke, so the blade was unable to retract. I was so nervous using it that I went out the next day and bought a new one. I like the new one. It's an Olfa with ergonomic handle and the blade retracts automatically!
