Gyuto 230mm GoMai Stainless Clad Integral I-Beam Frame Handle Mamoth Ivory

$4,676.00

This handmade kitchen knife is a true one-of-a-kind creation from the renowned French blacksmith Antoine Kniamen. A stunning fusion of Western and Japanese design, the knife's hybrid profile offers unparalleled versatility for both professional chefs and home cooks alike. The edge profile borrows from the Japanese Gyuto, but with a slightly more bellied curve, allowing for fluid rocking motions while still supporting precise chopping techniques. Taller than a traditional Gyuto, the additional height offers greater knuckle clearance and a more commanding presence on the cutting board. This dynamic blend of design elements results in a knife that feels equally at home slicing through delicate herbs or breaking down larger cuts of meat with ease. Whether on display in a fine dining restaurant or as a centerpiece of a home kitchen collection, this knife’s utility and elegance are unmistakable.

The knife's geometry is a masterclass in precision craftsmanship. It features a highly tapered spine that provides exceptional balance, making it feel nimble and responsive in the hand. This thoughtful design gives the user incredible control during use, offering the precision required for delicate tasks and the heft necessary for more demanding cuts. The finely shaped convex bevels further enhance its cutting performance by reducing friction as the blade moves through ingredients, ensuring smooth, effortless slicing. Food release is excellent, minimizing sticking and improving efficiency during prep work. The heart of the blade is forged from a composite steel, with a core of Apex Ultra—a high-carbon steel renowned for its edge retention—encased in layers of stainless steel and nickel. This construction not only provides superior cutting power but also ensures rust resistance and structural integrity. The black-etched finish, contrasted against the bright silver layers of nickel and stainless steel, creates a visually striking and highly functional work of art.

The handle is an equally impressive blend of artistry and engineering. Antoine’s signature "I-Beam" design features an intricately TIG-welded and polished integral bolster, offering a seamless transition from blade to handle. The scales are crafted from a rare and highly sought-after set of mammoth ivory with mesmerizing blue streaks. These natural blue hues are a result of millennia-long mineralization, where iron and other minerals permeate the fossilized ivory, leaving behind vibrant and unique coloration. Each handle is, therefore, a singular masterpiece of natural art. To complement this visual splendor, the handle also incorporates blackened steel accents that provide a matte texture for a secure, slip-resistant grip. The matte finish resists fingerprints, maintaining its sleek, clean appearance even with frequent use. Together, these elements showcase Antoine Kniamen’s masterful approach to functional design and artistic expression. This knife’s beauty, balance, and performance make it a remarkable achievement—a shining example of Kniamen’s craftsmanship and a glimpse of more exciting creations to come.

Product Care:

Cleaning: Clean by hand with warm water. Avoid wetting the handle when possible. 

Sharpening: We advise using whetstones to sharpen your knives and a honing rod or steel to maintain the burr between sharpening sessions. 

Reactive Steels: Reactive steels like Aogami Super, Apex Ultra or one of the many premium reactive German and Swedish steels are susceptible to rust if not properly cared for. In this case we advise that you keep the knife dry between uses and when storing the knife for longer periods wiping the knife blade with Tsubaki oil or another food safe oil is a wise choice. This will not stop a patina forming on the blade, but it will stop rust. A patina can be a beautiful personal feature on your knife and helps to stop rust forming. So, dry your knife regularly between uses, store in a dry place and apply some Tsubaki oil from time to time when storing for long periods. 

A reference guide to steel types

Handle Care: If you have a knife with a non-stabilised wooden handle, you can apply Tsubaki oil or another food safe oil to your handle from time to time. Food safe wax can be applied to both stabilised and no-stabilised wooden handles. Never apply hot wax or oil as you risk warping or damaging the handle.
