Review on 🔪 High-Quality Olfa Rotary Blade Refill 60mm - Replacement Blade for Precise, Effortless Cuts - 1/Pkg by Doris Tran

This is a mystery. This blade was dull the first time I used it. My 45mm cuts fabric like a dream. A few weeks later I'm still using the same 45mm blade. This 65mm blade must be defective. My husband and I spent hours trying to figure out what was going on. It's a secret. I have no idea why. Update August 2020 - This was by no means a new blade. I'm still using the same 45mm blade after 2 months. The 2020 blade is a bit fishy and I don't think this is Olfa's new blade.
