Olfa 45mm 교체용 로터리 블레이드 5팩

The plastic case is a nice bonus for keeping them organized, and the carbide steel edges stay sharp through several large cutting projects before needing a swap.

These blades cut through multiple layers of denim like butter, and the tungsten carbide steel definitely holds its edge longer than the cheaper brands I tried. The little plastic case is actually handy for keeping them organized in my sewing drawer.

I’ve been using these blades for months now, and the tungsten carbide steel keeps them sharp far longer than cheaper alternatives. They cut through multiple layers of fabric without snagging. The five-pack in its own case is convenient for organizing my craft drawer.
