Review on 🔪 10 Pack of 45mm Rotary Cutter Blades by KISSWILL - Compatible with Fiskars, Olfa, Martelli, Dremel, Truecut, DAFA - Replacement Blades for Quilting, Scrapbooking, Sewing, Arts & Crafts - Sharp and Long-lasting by Hannah Curi

I don't know about the durability yet, but the blades fit my Fiskars slicer right out of the box. They don't have all the cutouts that other blades have to make them versatile, so I think they work better in that direction in the long run. I cut through some pretty tough stuff to test it and it went straight through - the blade is nice and sharp from the start. I'll learn more about durability when I start the project, but they're definitely a lot more affordable than Fiskars blades right now. I'm satisfied so far.
