Review on High-Quality Cut 10x 45mm Rotary Cutter Replacement Blades by Morgan Gilmore

I am a quilter and have ordered two packs of these blades. These were the worst knives I have ever used in 25 years of quilting. You should be ashamed to sell them. As I had a few in a different package from a "reliable" retailer, I didn't open them until July 1st. I tried both packages and they were all bad. I bought these two packs for my quilter friends and I'm embarrassed. I ruined most of the expensive fabrics trying to get them to work. To shame! It's too late to send them back now. I hope nobody else buys these really bad blades.
