Is it just me? My rotary blades don't seem to last as long as they use to. They seem to only stay sharp for only one project, they use to last for at least 4-5 projects.
I agree with you...The blades dull very quickly....They seem thinner....
I started to have problems then treated myself to a new cutting mat AND a 60mm Olfa cutter, no problems at all now. I would really recommend investing in the 60mm if you do a lot of cutting, which I do.
I don't seem to have a problem with my rotary blades, and I have cut loads of fabric without changing the blades. Have you checked to see if the blades are put in backwards? That can make a big difference. It's worth a try. Hope you have better luck.
Do blades have a front and back? How can you tell?
