Kai 滾輪裁刀刀片

Cut through a double layer of thick denim without any snagging on the first try, and the tungsten edge still feels like it’s brand new after a full day of quilting. The 45mm size fits my old cutter perfectly, which is a relief since I was worried about compatibility.

Just swapped in this blade and it sliced through a stack of 8 cotton layers like they were butter. The Japanese steel is noticeably sharper than my old generic blades.

I’ve been using this 45mm blade for a few weeks now and it’s still slicing through multiple layers of cotton like it’s brand new. The tungsten steel edge definitely holds up way better than the cheaper blades I used to buy.
