Review on 10PCS Premium Spare Replacement Blades for 60MM Rotary Cutter by Sopito - Enhanced Sharpness, Perfect for Heavy Duty Use, Quilting, Patchwork, Crafts, and Sewing by Jessica Lewis

When I first got them and tried to use them, my cutting knife wobbled and jumped around because of the protrusions in the middle of these blades. The first picture on the left shows a real Fiskar blade and on the right a Revain blade. I was so disappointed that I couldn't use them. Then my brain cells decided to make a living, and it dawned on me to turn the screw in the center of the rotating blade so the nut was on the back of the knife. Voila! Problem solved! They cut better than the expensive ones. 🙌🏿 I'm really embarrassed because I suspect that I was wrong about the screw on the cutter all these years, but still thought I should share it in case someone else had the same problem. 😬😂
