Professional Straight Razor for Men - Kiru

Kiru takes its name from the Japanese verb "to cut" — fitting for a razor whose entire design serves the edge. This is a traditional straight razor for professionals and committed home shavers who want precision they can maintain for years.

The Steel That Sets It Apart

The handcrafted blade is ACRM carbon steel hardened to HRC 58-59. That hardness range is the sweet spot for a straight razor: hard enough to take and hold a genuinely keen edge, tempered enough to strop back to sharpness easily. The result is a smooth, precise shave pass after pass.

Natural Wood, Natural Balance

The handle is natural wood with rich tones and a sleek, ergonomic shape. Its balanced weight makes each stroke feel controlled and effortless — important when you're navigating a jawline with an open blade.

Care and Use

The Kiru arrives sharpened and ready to shave out of the box. To keep it that way, run the blade over a strop before each shave — a thirty-second habit that keeps the edge razor-keen and pushes honing far into the future.
