Review on 🔪 Ultima Rotary Cutter Blades - 10 Pack, 28mm, 45mm & 60mm - Fits Fiskars, Olfa, Martelli and TrueCut - Perfect for Quilting Fabric, Leather, and More! by Heather Shaw

These blades just ain't bad. I bought these to replace Olfa and Fiskars knives and the difference is huge! So far I've used three blades. The first didn't cut evenly at all - constantly "skipped" - and I couldn't use it. I threw it away. The second was much better. Cuts straight but dulls fairly quickly. I cut out about 150 sets of fabric for face masks, after which I had to discard them. The third blade jumped just like the first, but I was still able to use it. I only had to pass the blade across the fabric twice or cut off missing areas every few inches. I'd say "You pay for what you get." These blades can be used, but they're not the best. In the future I will use Olfa knives and even Fiskars.
