Yep, make sure you get your tetanus shot. I had a rotary cutter "incident" on Wednesday this week and am glad to know my blade was "sharp enough" to cut nicely through fabric but not so glad for my my left index finger AND the finger nail. The DH took me to the emergency room - first thing was tetanus shot and second was...well they bandaged it up and said that the partial sliced finger piece couldn't be stitched but it was a "nice clean 1/4" cut" and it will heal and look just slightly strange for a while. Was back quilting today - Aleve helps.
