Sometimes if your blade rides too much against the ruler it can dull them quicker...I sometimes knick mine on the ruler, too :roll:
when I first started a few months ago I did this alot...I am getting better about not doing it though. I used the rotary cutter years ago doing diapers and that blade lasted forever.
