I have had to replace my 45 mm blade on my OLFA cutter five times this week and I am trying to figure out the problem. I am getting nicks in the blades, I know that much.
I thought it might be dirt or sand as I am cutting on the floor (but I always cut on the floor and this has never happened before) so I vacuumed carefully, shook out my fabric (I'm using flannel which is a first for me if maybe that means something?), cleaned my cutting mat, replaced the blade again, and it's still happening.
There is a nick on my cutting mat, could it be the nick on the mat that is damaging blades? I don't see how though.
Could it be the flannel somehow?
Thanks for any ideas...
