This extraordinary blade is the creation of world-renowned Austrian blacksmith Benjamin Kamon, known for his unique artistry and meticulous craftsmanship. Featuring Benjamin’s signature Gyuto profile, the blade is designed with convex bevels and a walkschliff tip, making it a versatile tool for precision slicing, chopping, and intricate cuts. The blade showcases Kamon’s iconic Wave pattern, enhanced with a striking black etch and finished with an oil slick sheen. Paired with the knife’s sleek blue and black ebonite handle, this aesthetic harmony reflects both elegance and utility.

The blade’s durability and cutting performance are enhanced by an innovative heat-treatment process that ensures uniform heat distribution and a finely tuned carbide structure. This results in a remarkable 67 HRC hardness, enabling the knife to maintain its exceptional edge retention and durability over extended periods of use. Further enhanced by cryogenic treatment, the blade boasts unparalleled toughness, making it a reliable companion for professional chefs and culinary enthusiasts alike. The Apex Ultra steel, celebrated for its high-carbon, low-alloy composition, provides a perfect balance of strength and flexibility, ensuring extraordinary cutting performance and longevity.

The handle, crafted from a singular piece of ebonite, adds to the knife’s exceptional design and functionality. Ebonite, a vulcanized rubber, is not only incredibly durable but also offers a comfortable grip and resistance to wear and environmental changes. Complementing the handle are polished black zirconium “torpedo end caps,” a signature feature of Kamon knives, which enhance the ergonomic feel while adding a touch of sophistication. For safe and easy transportation, the knife is accompanied by a custom-fitted saya, further emphasizing its practicality. This one-of-a-kind piece exemplifies world-class design, delivering exceptional high-performance cutting and unparalleled ergonomics, making it a treasure for collectors and culinary professionals alike.

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.

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

Mono Steel

A knife forged from a single piece of steel — no laminations, no clad layers. The simplest and most direct construction. The entire blade is the cutting steel, with no softer outer jacket to protect or contrast it. Most contemporary Western kitchen knives in carbon and stainless steel are mono-steel constructions, as are honyaki and most European bladesmith work.

The trade-off is straightforward: mono-steel knives are easier to forge, sharpen, and reason about, but the entire blade carries the cutting steel's properties — including its reactivity if it's a clean carbon. There is no soft jacket to protect a more brittle core from impact, so the heat treatment and geometry have to do all the work.

Grind

Convex

A grind whose bevel bulges outward in a gentle curve from spine to edge, rather than running flat. That extra steel directly behind the edge makes a convex grind notably strong and resistant to chipping, while the curved geometry helps food release and lets the blade glide through dense ingredients with less wedging than a flat grind.

The strength comes at the cost of ultimate thinness and ease of maintenance. A convex edge has more metal behind it, so it is not quite as effortlessly keen as a thinly flat-ground edge, and it is harder to sharpen freehand — holding the curve takes a stropping technique or a deliberate hand rather than a single fixed angle. The reward is an exceptionally tough, smooth-cutting edge.

Handle construction

Takedown

A takedown is a hidden-tang construction built to come apart. The tang passes through the handle and is drawn up by a threaded fitting — a nut at the butt, or a pommel that screws down — so the handle can be dismantled and re-fitted rather than being permanently bonded in place. Everything else follows the hidden-tang pattern: a concealed tang inside a one-piece handle, with no steel showing along the grip.

The point of the design is serviceability. Because the handle is mechanical rather than glued, it can be taken off for thorough cleaning and drying, swapped for a different material or profile, or replaced entirely if it is ever damaged — all without destroying the original fittings. It is the construction to choose for a knife meant to be maintained and kept for the long term, and for owners who like the option of changing a handle later.

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.
