The rotary cutters we use are discribed as a rolling razor blade. Well what I have bought so far I consider junk. For the price of one blade your lucky to be able to cut one quilt. I just had the second handle fall apart.
Today I am going to the hardware store and look for a cutting knife that has replaceable blades. I know there are all kinds, one thing they have in common is they're sharp. I want to get one that uses inexpensive blades. I will post later and let everyone know what I find. :wink:
