Review on 45mm Rotary Cutter Blades for Quilting - 5-Pack, Ideal for Precision Cuts by Nicole Mcleod

If I could give these spinning blades zero stars I would! The first blade was fine, but only stayed sharp enough to cut a few 12" blocks. I made the mistake of taking them to a stash and thought my cutter was broken, I tried 3 different blades in this set and they were all so dull they couldn't cut through a single layer of moda fabric! For Lucky I got a blade left by Olfa and I was able to switch to it and cut (one queen size quilt and one double size quilt) for three days. Don't waste your money on these blades.
