I have serious arthritis in my shoulder (need a shoulder replacement) and had reached the point where I couldn't use any of my rotary cutters. I had to get my husband to cut any fabric I needed and that was very frustrating for me. After some research, last year I ordered the Martelli rotary cutter and I can once again cut my fabric. I still can't cut all day, but it is wonderful to be able to cut what I need as I need it. It may be different with wrist or hand problems, but I'm thrilled with my cutter. The blade is so sharp and lasts so much longer than any other brand I've tried in my other cutters that I will only use Martelli replacement blades in mine.
