Ruby F. ★★★★★ Oct 21, 2026

The 45mm blade cut through four layers of denim without any snagging, which saved me so much time on my last project. These Japanese steel replacements are noticeably sharper than the generic ones I was using before.

Grace ★★★★★ Oct 19, 2026

Cut through a stack of vinyl and two layers of denim on the first try — the 45mm blade held its edge way longer than I expected. The SKS7 steel feels noticeably sturdier than the cheap ones I've burned through before.

I was a little skeptical about cutting leather with a rotary blade, but the Japanese steel on these handled three layers of thick vinyl without any snagging. The 45mm size is perfect for my daily fabric cutting, too.
