Dieses einzigartige, handgefertigte Küchenmesser ist das Werk des renommierten Messerschmieds Karol Karys, der für seine kühne, brutalistisch inspirierte Handwerkskunst und seine kompromisslose Liebe zum Detail bekannt ist. Dieses Stück ist eine zeitgenössische Neuinterpretation des japanischen Kiritsuke – einer Hybridklinge, die traditionell sowohl zum Schneiden als auch zum Stoßschneiden verwendet wird –, die Karol in ein markantes, modernes Präzisionswerkzeug verwandelt hat. Sein Rücken weist eine aggressive Verjüngung auf, die sich zur Spitze hin rapide verjüngt und dem Messer eine optische Spannung und Balance verleiht, die sowohl für die Leistung als auch für die Ästhetik spricht.

Unter seinem skulpturalen Äußeren verbirgt sich eine sorgfältig ausgeführte Geometrie: Dünne konvexe Fasen gehen in eine Walkschliff-Spitze über und sorgen für ein feines, reaktionsschnelles Gefühl an der Vorderseite der Klinge. Die Kombination aus ausgeprägter Verjüngung und diesen leistungsstarken Schliffeigenschaften ergibt ein Messer, das mühelos durch Zutaten gleitet – mit minimalem Widerstand durch Proteine und Obst und Gemüse. Diese Klinge ist für Profis und Hobbyköche gemacht, die Schneidleistung ohne Kompromisse beim Charakter schätzen.

Die Materialien unterstreichen die Einzigartigkeit des Stücks. Geschmiedet aus einer San Mai-Konstruktion mit Schmiedeeisenverkleidung über Apex Ultra-Kernstahl bietet das Messer sowohl optische Dramatik als auch höchste Schnitthaltigkeit. Der Griff ist ein herausragendes Merkmal: Karols charakteristisches Profil aus sandgestrahltem Walnussholz, gepaart mit einem Mokume-Gane-Kronen, der ihm eine handwerkliche Note verleiht. Jede Oberfläche trägt seine brutalistisch inspirierten Texturen – roh, fühlbar und zutiefst ausdrucksstark.

Blade type

Kiritsuke

切付

Traditionally a master's knife — a long, straight-profiled blade with a distinctive angled, reverse-tanto tip, historically a single-bevel knife reserved for senior chefs. In its modern double-bevel form (sometimes called a kiritsuke-gyuto or kiritsuke-santoku) it functions as a flat-profiled all-rounder: the long straight edge favours push cutting and the dramatic angled tip handles fine point work.

The kiritsuke asks more of its user than most blades. The flat profile rewards precise, controlled technique and resists rocking, and the true single-bevel version demands specific sharpening skill and a committed hand. Much of the knife's reputation is cultural as well as functional, and the double-bevel versions are far more forgiving for everyday use.

Cutting edge steel

Origin
Austria (ApexUltra project — developed by Larrin Thomas, Marco Guldimann and Tobias Hangler; FFG-funded, associated with Messerschmiede Hangler)

Apex Ultra is one of the most carefully engineered non-stainless kitchen knife steels in modern circulation — a steel designed from the ground up specifically for handmade knives, rather than borrowed from another industry. It was developed by metallurgist Larrin Thomas together with smiths Marco Guldimann and Tobias Hangler. It is a low-alloy carbon steel — roughly 1.25 percent carbon, 2.6 percent tungsten, 1.5 percent chromium and a 0.4 percent vanadium addition, with manganese and silicon kept low. That composition is tuned for high purity and a fine, evenly distributed mix of chromium-enriched iron carbides, tungsten carbides and vanadium carbides — the structure that lets it hold a very hard edge without the coarse carbides or plate martensite that sap toughness in other high-hardness carbon steels.

What this means for a cook is unusual permission. Apex Ultra carries very high toughness in the 66+ HRC range — the highest of any knife steel its developers have tested at that hardness — so you can ask a maker to grind it thin and run the heat treatment hard, and the edge will hold far longer than the carbon steels smiths usually forge, without microchipping. It forges and forge-welds much like 52100 or 1.2562, sharpens cleanly on natural and synthetic stones without needing diamond plates, and its modest chromium slows patina a little — though it is not stainless and should be cared for 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

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

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.
