I used to put off changing blades because I always had so much trouble doing it. I never seemed to get the blade on the first time so it wasn't skipping even worse than the old one. I finally broke down and bought the Olfa quick change rotary cutter. I love it!!!!!! I used a 50% coupon at Joann's and it was worth every penny.

And as others have mentioned, I use my discount coupons to buy blades at 40 or 50% off.
