Creative Grids ロータリーカッター替刃 45 mm - 2枚入り CGRRB45-2

Bought two packs because I go through blades fast, and these carbide steel ones definitely hold an edge longer than the cheap alternatives I tried. They fit my old 45mm cutter perfectly and cut through multiple layers of fabric without snagging.

I was pleasantly surprised at how smoothly these 45mm blades cut through multiple layers of cotton without any drag, and they fit perfectly on my cutter. After a full afternoon of cutting, the edge still feels as sharp as when I first opened the pack.

The carbide steel edge held up through an entire afternoon of quilting without a single snag, and the blades fit my older cutter perfectly. I’ve already ordered a second pack because the first one is still sharp enough to reuse.
