Kotaro Hair Cutting Shears Set (Hair Cutting and Thinning Shears) - Open Box

The Kotaro set pairs a handmade cutting shear with its matching thinner, both forged from Japanese 440C stainless steel and finished with a Japanese-style convex edge hardened to 60-61 HRC. That hardness band is the sweet spot for 440C: hard enough to hold a razor edge through slide cutting on wet or dry hair, forgiving enough to resharpen cleanly for years.

Ergonomics get equal attention. The offset handle with a removable finger rest keeps your hand, wrist, and elbow in a neutral line, so a full book of clients doesn't collect as fatigue in your forearm. The thinner removes bulk, softens weight lines, and adds texture while keeping you in complete control of how much comes out.

This is an open-box set — the same tools and the same lifetime warranty against manufacturing defects at a friendlier price.
