Creative Grids ロータリー刃 60 mm - 5枚入り CGRRB60-5

These blades cut through multiple layers of quilting cotton like butter, and I love that they fit my Olfa handle perfectly. The carbide edge is noticeably sharper than standard steel ones I've tried before.

The carbide steel edge chewed through a stack of cork sheets without a single snag, and the 60 mm size fits my old cutter perfectly. These stayed sharp through a full day of quilting prep, so the five-pack feels like a solid value.

I’ve been using these 60 mm blades for a few weeks and they cut through multiple layers of fabric without any fraying. The carbide steel really holds its edge much longer than the standard blades I used before.
