This is an absolute beast of a blade, 250mm by 65mm. Workhorse, workhorse, workhorse! At the centre, a rock-solid core of 1.2562 carbon steel hardened to 64HRC. A beautiful steel with great edge retention, sharpen-ability, and a stunningly sharp and bighting edge.

The photos don’t really do it justice, Tomislav gives his knives one of the most comfortable and elegantly facetted handles around and although it may not look like it, the stepped integral handle is actually very comfortable to hold and a classy look on such a beast of a blade. On this blade it’s a beautiful, stabilised, walnut burl.

This monster has curves! The geometry and balance are perfect! It’s not easy to see, but the knife features a through tang, finishing at the end of the handle in a perfectly flushed steel end cap. A highly tapered spine makes for a versatile cutting action and the huge blade height means that although the spine is quite thick, the bevels are quite thin behind the edge.

The blade is finished in a contrasting cobination of forge finish and kasumi polish. An amazing piece from one of our favourite bladesmiths.

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

1.2562

High-alloy tungsten tool steel

Typical HRC
62–65
Corrosion class
Carbon
Production
Conventional
Origin
Germany (DIN 80WCrV8)

1.2562 is a more heavily tungsten-alloyed German tool steel with approximately 0.80 percent carbon, 0.3 percent chromium, 1.85 percent tungsten, and a small vanadium addition. It sits at the high-W end of the conventional kitchen knife steels and produces an unusually wear-resistant edge for a non-PM, non-stainless carbon steel.

In a finished knife it runs at 63 HRC and behaves like a tougher, somewhat keener relative of 1.2442. Edge retention is meaningfully better than the simple carbons; toughness is good for the hardness; patina behaviour is conventional. The trade-off is sharpening: the W carbides are noticeable on softer stones, and the steel benefits from a vitrified or natural fine stone in finishing.

It is comparatively uncommon in finished kitchen knives but well regarded among makers who specifically want a high-tungsten European carbon. Among the makers Modern Cooking carries, Tobias Hangler and Dominik Filip work in 1.2562. Treat it as an enthusiast's choice.

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.
