When it comes to a Brook Turner blade its performance first design all the way. Brooks knives tend to feature geometry that is inspired by the Japanese style. So, on this classic Wa style Gyuto we find a thin blade, 3mm and less, subtly tapered, relatively low blade height and a classic profile. These knives are a pleasure to use, its the type of cutting experience were you forget about the knife as it falls into the background reliably doing its job without fail.

Brook has developed a signature style that centres around premium steels, house forged laminates and incredible, exotic woods, often sourced from him home country Australia. On this knife we have a beautiful wrought iron clad 26c3 blade. A lovely satin polish completed on whetstones, and brute de forge at the spine complete this simple classic. The handle, a classic octagonal hidden tang in Tasmanian Blackwood. 

Brook is an extremely talented craftsman, his work features an unquestionably high standard of fit and finish. This is the kind of knife that is an absolute delight to work with and looks incredible.

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

26C3

High-carbon, low-alloy fine-grain steel

Typical HRC
63–67
Corrosion class
Carbon
Production
Conventional
Origin
Sweden (Sandvik / Alleima)

26C3 is one of the most quietly important kitchen knife steels of the past decade. Originally engineered by Sandvik as a razor steel — its lineage runs straight to UHB-20C — it carries about 1.25 to 1.30 percent carbon, very low manganese and sulphur, and a small chromium addition to control grain size. The result is a steel that hardens cleanly into the mid-sixties HRC while retaining genuinely useful toughness for its hardness, an unusual combination outside the powder-metallurgy world.

For the cook, 26C3 sharpens the way the best Japanese white papers sharpen — a quick burr that wipes off cleanly, and a polished edge that holds a screaming apex without microchipping. Toughness at 64 HRC is comparable to or better than 52100 at the same hardness in published testing, which is part of why the Larrin-Thomas-and-friends generation of makers gravitated to it; it lets you grind thinner without paying for it later. Like all clean carbons, it patinas willingly and benefits from a wipe between tasks.

26C3 has become something of a default among UK and European bladesmiths who want a no-compromise carbon edge, and it is the chemical parent of SheffCut, which adds a sliver of niobium to refine grain further. Among the makers Modern Cooking carries, Birch & Bevel, Karol Karyś, Jonas Johnsson, Tobias Heldqvist, Brook Turner, and Fredrik Spåre work in 26C3. It is one of the few non-stainless steels you can recommend to a cook coming from VG-10 without apology.

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.
