An incredible Gyuto 260mm knife features a tall K-Tip profile. The blade features a subtle distal tapering, with a ridged spine that makes it perfect for working through tougher materials like root vegetables. The edge is nice and thin, it's not a delicate edge, but its thin enough to ensure a balance between great cutting performance and durability at the same time. Well balanced and satisfyingly weighted. At the core we find premium SheffCut steel, which is essentially 26C3 with added Niobium for improved wear resistance.

The blade features a unique and iconic copper etched wrought iron cladding. The etching significantly improved the wear resistance of the wrought iron and creates a beautiful high contrast look on the blade. Pared with copper and ironwood, this is a stunning piece from Konstantinos.

At Modern Cooking we pride ourselves on curating some of the best work from around the world. High performance and quality craftsmanship always come first. Some of the highlights in terms of quality on this blade are the of course the geometry and forging quality of the blade, but also an heirloom fit on the copper bolster and the beautifully ergonomic shaping of the handle itself. Konstantinos is a very talented craftsman and we are thrilled to have him join our Collectors Selection.

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

SheffCut

High-carbon, low-alloy fine-grain steel with niobium

Typical HRC
63–65
Corrosion class
Carbon
Production
Conventional
Origin
United Kingdom (GFS / Sheffield)

SheffCut is one of the recent entries in the modern carbon-steel revival: in essence, 26C3 with a small (~0.10 percent) niobium addition for further grain refinement and a touch more wear resistance. The steel is produced and marketed by Sheffield specialty supplier GFS and has been adopted enthusiastically by the British and American forging communities.

For the cook, SheffCut behaves almost identically to 26C3: a clean apex, easy sharpening, edge retention competitive with the best non-powder carbons, and toughness good enough to allow thinner geometries than the simple carbons can support. The niobium addition is genuine but subtle — a small but measurable improvement on what was already a very strong steel. Patina behaviour is conventional.

SheffCut is often presented as a "Sheffield carbon revival" — a deliberate reframing of UK steelmaking in the post-Sheffield-decline era — and it is, narratively as well as metallurgically, a worthwhile project. Among the makers Modern Cooking carries, Konstantinos Noulis works in SheffCut. It is the kind of steel a customer ends up with after asking for "the best non-stainless edge a UK maker can give me."

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.
