This one-of-a-kind Gyuto, handcrafted by renowned bladesmith Simon Krichbaum exclusively for the MCx Design Studio, represents a masterful dialogue between Japanese tradition and modern performance. Krichbaum’s refined interpretation of the Gyuto form reveals a blade that is both purposeful and elegant: an aggressively tapered spine flows into a finely pointed tip, offering balance, agility, and precision in equal measure. The profile invites confident control across all tasks—from delicate slicing to decisive chopping—while maintaining a graceful, contemporary silhouette that reflects the MCx studio’s design ethos of restrained minimalism and uncompromising function.

At the heart of this piece lies a GoMai construction with an Apex Ultra core, clad in stainless steel and separated by a nickel diffusion barrier. This pragmatic yet refined combination delivers a blade of exceptional sharpness, edge stability, and corrosion resistance. The geometry features a low grind, hand-finished on natural stones to achieve a luminous kasumi polish below a dark kurouchi upper finish. The resulting contrast embodies both aesthetic harmony and technical depth—each surface telling the story of countless hours of shaping, refinement, and intuition. Together, the highly tapered profile, low-drag bevels, and fine balance create a knife that moves effortlessly through food, offering feedback and flow that only the most carefully executed handmade blades can achieve.

Completing the composition is a Rokkaku Hanmaru handle crafted from richly figured Australian Red River Gum, paired with a buffalo-horn ferrule that lends visual warmth and tactile grace. The hidden-tang construction preserves balance and purity of form while ensuring strength and comfort in extended use. Every detail—from the alignment of the bevels to the gentle transitions of the handle—reveals Krichbaum’s meticulous craftsmanship and the MCx Design Studio’s pursuit of functional artistry. Presented with an MCx tote and studio insignia, this singular Gyuto stands not only as a high-performance culinary tool but also as a contemporary expression of the enduring bond between maker, material, and design.

Blade type

Gyuto

牛刀

The Japanese take on the Western chef's knife, and the most versatile blade in a modern kitchen. A gyuto carries a long, gently curved edge — most often 210 to 270 mm — that allows both push cuts and a rocking motion, with a pointed tip for fine work and enough height at the heel to keep knuckles clear of the board. It handles proteins, vegetables, and herbs without complaint, which is why most cooks reach for it first.

Compared with a European chef's knife, the gyuto is usually thinner, harder, and lighter, ground to a finer edge that rewards good board technique and regular honing. That same thinness is the trade-off: the edge is less forgiving of bone, frozen food, and twisting cuts, and it asks for a little more care in maintenance in exchange for its keenness.

Cutting edge steel

Apex Ultra

Low-alloy fine-grain carbon tool steel

Production
Conventional
Origin
Austria (developed by Tobias Hangler and Marco Guldimann; project led by Hangler at Messerschmiede Hangler)

Apex Ultra is one of the most carefully engineered non-stainless kitchen knife steels in modern circulation, and the project of an Austrian smith — Tobias Hangler — who set out, with Marco Guldimann, to design a steel for the kitchen rather than borrow one from another industry. It carries roughly 1.25 percent carbon, around four percent chromium, modest tungsten and molybdenum, and a small vanadium addition. The composition is tuned to produce a fine, evenly distributed carbide structure that supports hardness up to 67 HRC while delivering toughness comparable to 52100 at the same hardness — a combination that is the entire point of the steel.

What this means for a cook is unusual permission. You can ask a maker to grind an Apex Ultra knife thin enough that a White #1 owner would call you brave, then ask for the heat treatment to land at 65 HRC, and the resulting edge will hold for longer than Aogami Super without microchipping. It sharpens cleanly on natural and synthetic stones alike and patinas slowly because of the chromium content, though it is not stainless and should be treated as a carbon steel.

Apex Ultra has become a signature steel of the European maker community, and the Modern Cooking catalogue carries an unusually deep bench of smiths working in it. Tobias Hangler himself heads that group, alongside Marco Guldimann, Benjamin Kamon, Martin Huber, Jonas Johnsson, Karol Karyś, Birch & Bevel, and MCx. It is genuinely a step forward — one of the relatively few cases where the marketing claims and the underlying metallurgical data are saying the same thing.

Blade construction

Laminated Steel

A category covering knives built from multiple layers of different steels forge-welded together. The hard cutting steel is sandwiched between softer outer layers (cladding) that protect the core, add toughness, and often contribute visual contrast.

The most common laminated constructions in the Modern Cooking catalogue are:

SanMai (三枚) — three layers: hard cutting steel in the centre, softer cladding on both sides. The traditional and most common form.

GoMai (五枚) — five layers: a hard core, two intermediate layers, and two outer layers. Adds visual depth and structural complexity.

KuMai (九枚) — nine layers: similar logic, with more cladding layers for additional pattern and structural variation.

GoMai and KuMai are often chosen not only for the additional layers and visual depth, but also because the intermediate layers can act as a nickel diffusion barrier — limiting carbon migration out of the core into the cladding during forge welding, and protecting the core's intended carbon content through the heat of the forging process.

In all cases the cutting performance is determined by the core steel; the outer layers are cosmetic and structural. The lamination contributes corrosion protection (when a stainless jacket clads a carbon core), reduced reactivity, and the visible boundary between core and cladding that gives the knife its character.

Grind

Walkschliff

A traditional Solingen grind — also called a kettle or kessel bulge grind — in which the blade is hollowed high on the side so its thickest point sits a little below the spine rather than at it. Below that bulge the steel is taken down to an extremely thin, finely convexed cutting edge, combining the rigidity of a thick upper blade with the keenness of a very thin one.

The Walkschliff is among the most demanding grinds to execute, historically reserved for the finest German knives and requiring years of a grinder's experience to do well. For the buyer it is a high-craft European alternative to the thin flat grinds of Japanese knives — strong, stable, and keen — but it is a hand-ground specialism, and a knife that carries it is priced for the skill it took to make.

Handle construction

Hidden Tang

A construction in which the tang runs into the handle but stays concealed inside it, rather than showing between two scales. A narrower tang — a full-length stick or a shorter projection — is set into a drilled or burned channel in a one-piece handle and secured with adhesive, a friction fit, or a threaded fitting drawn up against the blade. This is the traditional construction of Japanese wa-handles and many European hidden-tang knives.

The design puts the handle material in charge of the look and feel: a single piece of wood, horn, or composite — often with a ferrule or spacers at the front — is shaped into any cross-section the maker wants, from the classic octagonal and D-shaped wa profiles to fully rounded Western forms. With no steel showing along the grip, the handle can be slim and light, and is frequently made to be removed and replaced, with the balance sitting toward the blade.

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 premium reactive German and Swedish steels are susceptible to rust if not properly cared for. Keep the knife dry between uses and when storing for longer periods, wiping the blade with Tsubaki oil or another food-safe oil is a wise choice. A patina can be a beautiful personal feature on your knife and helps to stop rust forming.

Handle Care: For non-stabilised wooden handles, apply Tsubaki oil or another food-safe oil from time to time. Food-safe wax can be applied to both stabilised and non-stabilised wooden handles. Never apply hot wax or oil as you risk warping or damaging the handle.
