Mazaki Blue 1 Mizu-Honyaki Gyuto 240mm w/ Burl Handle Wenge Saya

The Mazaki Blue 1 Honyaki Gyuto 225mm with Burl Handle and Wenge Saya is a rare and powerful expression of one-man Japanese craftsmanship, forged by Naoki Mazaki in Sanjo, Niigata.

Mazaki is one of the standout independent makers from Sanjo’s new generation. Originally from Hokkaido and not born into a blacksmithing family, he trained at Yoshikane Hamono before establishing his own workshop. Today, he works largely by himself, handling the forging, grinding, heat treatment and finishing of his knives by hand. This gives his work a distinct individuality — direct, uncompromising and unmistakably personal.

Forged from Blue 1 carbon steel, this gyuto offers excellent edge retention, strong cutting feedback and the refined sharpening potential expected from high-end carbon steel. As a honyaki blade, it is made from a single piece of steel and differentially heat treated, making it significantly more difficult to produce than standard clad construction. The result is a blade with exceptional character, performance potential and a visible hardening line that speaks to the skill and control required in its making.

The 225mm gyuto profile offers an excellent balance between control and versatility. It is compact enough for precise board work, while still carrying the length and authority needed for slicing proteins, cutting vegetables and general professional kitchen use. Mazaki’s knives are known for their confident geometry, strong forging presence and handmade feel, and this Blue 1 Honyaki carries those qualities in a particularly special form.

This piece is completed with a richly figured burl handle and a dark Wenge saya, adding warmth, depth and elegance to the blade’s bold character. Rare in steel, construction and presentation, the Mazaki Blue 1 Honyaki Gyuto is both a serious cutting tool and a highly collectible piece from one of Sanjo’s most compelling independent makers.
