Olfa Endurance ロータリー刃 60 mm - 1枚 RB60H-1

Cut through six layers of denim like butter with this blade — it’s noticeably sharper right out of the package. The double endurance claim holds up so far, as I’m halfway through a huge quilting project without any dulling.

I was skeptical about paying more for a single blade, but after cutting through multiple layers of denim without any dulling, I’m convinced. It glides smoothly and hasn’t snagged once, even on heavy fabric.

Cut through four layers of denim like butter on my latest bag project, and the edge is still sharp after a full afternoon of cutting. This 60mm blade definitely lives up to the double endurance claim.
