I thought rotary cutters required their brand of blade only because of the notches. I love my Olfa ergonomic cutter so I would hate to change. Does Martelli fit other brands?
I have one of those large folding cutting stations from Joanns and have noticed that the mat on it seems to dull my blades more quickly. What I hate us to get a little nick that leaves a thread or two uncut on each turn. Cutting is not my favorite activity so it takes so much longer to have to go back and nip threads. Donna
