This one-of-a-kind Chef Knife is the work of Tobias Hangler, the Austrian metallurgist and bladesmith behind Messerschmiede Hangler in Gratwein — and one of the three people who developed Apex Ultra. At 235mm the blade takes the Western chef's form, with a curved belly that rocks naturally through herbs and aromatics and a 56mm heel that keeps knuckles clear of the board. At 227.9g it carries real presence, and the balance sits right at the maker's mark, so the knife pivots where a pinch grip meets the blade.

The spine runs 5.09mm at the heel, through 2.48mm at mid-blade, to 1.15mm near the tip — a substantial backbone that stays composed through the rear while the front feels nimble, a taper that gives the blade versatility across every cut. Wide convex bevels move the blade through dense produce with little drag and superior food release. The blade is an eleven-layer composite of the metallurgist's own design: an Apex Ultra core with pure nickel, 75Ni8 nickel steel and 1.4034 stainless stacked either side. The nickel sits directly against the Apex Ultra as a diffusion barrier, insulating and protecting the high-carbon core through the heat of the forge weld. Worked with Tobias's Denty texture and etched, it reads as crisp bright contours — pale islands scattered across a mottled grey upper blade — while below the texture the bevel is taken to a clean matte polish, so the ornament stops where the cutting begins.

Apex Ultra, the low-alloy carbon steel Hangler helped design specifically for fine kitchen edges, is hardened here to 66 HRC — the range the alloy was built around. It takes an acute edge and holds it, sharpens cleanly on whetstones despite the hardness, and will develop a patina like any carbon steel. The handle is a hidden-tang Western round in two-tone Australian mulga, the timber's pale sapwood set against its dark heart, with a brass bolster drawing the two together.

The result is a Western chef's knife with a metallurgist's thinking behind every decision: a maker working in the steel he helped create, at the hardness he designed it to reach. Performance-first design that cuts beautifully. We are proud to carry Tobias's work, and this one is made to be kept.

Blade type

Chef Knife

The Western chef's knife — the traditional European all-purpose blade, typically 200 to 250 mm, with a curved belly built to rock against the board. The pronounced curve from heel to tip suits a continuous rocking motion for mincing herbs and aromatics, and the blade is generally thicker, heavier, and softer than its Japanese counterpart, made to absorb hard and varied use.

That robustness is the trade-off. A Western chef's knife is forgiving, durable, and happy with bones, hard squash, and rough handling, but its softer steel and thicker grind mean it is rarely as keen as a comparable gyuto and needs more frequent honing to stay sharp. It is the dependable generalist of the kitchen — what it gives up in refinement it returns in resilience.

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.
