Gyuto 215mm GoMai Apex Ultra Core Integral Ironwood

Handmade by Dutch bladesmith Jeroen Knippenberg, this 215 mm Gyuto is a powerful expression of modern forged craftsmanship—bold, highly refined, and built for exceptional cutting performance. Featuring an integral construction and a beautifully executed Go Mai blade, it combines the visual depth of layered steel with the uncompromising feel of a serious working knife. The profile is confident and versatile, offering excellent control for everyday prep while still feeling precise and responsive through the tip.

At the core is Apex Ultra, a high-performance carbon steel prized for its very fine grain structure, outstanding edge stability, and exceptional sharpness potential. Hardened to 66 HRC, this knife is designed for those who appreciate a highly refined cutting feel and strong edge retention. The 5-layer Go Mai construction adds toughness and character around the hard core, while the acid-etched forced patina finish gives the blade a dark, dramatic surface and helps provide a measure of added protection in use. As a non-stainless knife, it will continue to develop character over time, rewarding good care with a uniquely personal finish.

The geometry is tuned for performance. A 4.89 mm spine at the heel gives the knife a strong and authoritative foundation, tapering through 3.28 mm at mid-blade to 1.1 mm near the tip for an excellent balance of power, stability, and precision. The convex grind promotes smooth cutting, low drag, and improved food release, while the 54 mm blade height offers comfortable knuckle clearance and a reassuring presence on the board. At 270.09 g, this Gyuto feels substantial and controlled in hand without sacrificing agility.

The handle is crafted from Desert Ironwood, a material long valued for its durability, richness, and natural figure. It complements the darker blade finish beautifully, adding warmth and a sense of understated luxury to the knife’s overall presentation. Ambidextrous and versatile, this is a knife for cooks and collectors who want the tactile rewards of high-hardness carbon steel, the visual depth of Go Mai construction, and the sculptural presence of an integral handmade piece.
