Olfa Rotary Replacement Blade 45mm

This blade sliced through six layers of cotton batting like butter—no fraying or snags at all. The tungsten steel edge feels noticeably sharper than the generic ones I used before.

I’ve been cutting through stacks of quilting cotton and this tungsten steel edge is still razor-sharp after a week of heavy use, easily slicing six layers without dragging. It clicks into my cutter perfectly and the packaging keeps it safe until you’re ready to swap.

Swapped out my old blade and this one sliced through a stack of four layers of cotton batting without any snagging or fraying. The tungsten steel edge really holds its sharpness noticeably longer than the cheap ones I’ve tried before.
