Although I cannot remember the original source, I read that the carpet cutting 45mm blades you can find at Harbor Freight are a great replacement for the 45mm blades you buy at a quilting or craft store. At about 75 cents a blade vs. 3 dollars or more a blade, I was so excited to give it a shot. So excited, in fact, that I bought 20 blades!
Today, I popped a brand new blade in the cutter, all excited to begin cutting the sashing strips for the Charlotte's Basket quilt. AWFUL! A brand new blade felt as good as putting a box cutter through cardboard. Not smooth at all. I hated it so much I took the old blade out of the garbage and put it back on! I drove about 30 minutes later to return my blades and purchase some at Joann's.
Moral of the story? The savings was surely not worth the poor cutting. Certainly if you are interested, give it a try. Don't buy 20 blades, lol!
Do any of you have any experiences with using a Harbor Freight blade? Any suggestions of a good place to buy 45mm blades online for a good price?
