Australian bladesmith Brook Turner continues to impress with this 210mm Gyuto. A GoMai construction, 52100 steel clad in wrought iron. The blade is finished with a mottled rustic kurouchi. The polished bevels revel the some beautiful wave like patterns in the wrought iron before hitting the black etched 52100 core.

We love the way Brooks treatment of the blade moves between rustic blacks and the lighter colors and details in the wrought iron and silver nickel. The 52100 steel gives the blade a nice sharp and toothy edge.

Brook's grinds flat, thin and sharp, with an edge profile that is predominantly flat. Nicely rounded edges and over premium quality fit and finish. The knife is finished with an unique Quan Dong octagonal grip a lovely contribution to an already very beautiful kitchen tool.

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

52100

Low-alloy chromium bearing/tool steel

Typical HRC
61–65
Corrosion class
Carbon
Production
Conventional
Origin
United States (AISI 52100); identical to 1.3505 and 100Cr6

52100 is the most respected non-stainless steel in the Western kitchen knife tradition — a chrome-bearing alloy that began life as a ball-bearing grade and has, over decades of custom-maker use, become a reference for what a thoughtful carbon steel should feel like. Roughly one percent carbon and one and a half percent chromium put it just below the stainless threshold but well within the territory where chromium meaningfully refines grain and tightens the carbide structure.

A good 52100 kitchen knife typically lands between 62 and 63 HRC. It sharpens with little drama on almost any stone, takes an edge as clean as the simple carbons, and holds it for longer thanks to those Cr-rich carbides. Toughness is excellent for the hardness — published comparative data positions it as one of the better-balanced carbon steels available, especially when the heat treat includes the cryogenic treatment that this steel rewards. It will patina, but more politely than a white paper, and it is forgiving enough that a single rinse-and-dry routine is usually enough.

52100 is the canonical choice for cooks who love carbon-steel feel but want a touch more refinement than 1084, W2, or even 80CrV2. It dominates the American custom scene and shows up across high-end stock-removal work from a wide range of forging custom shops. Among the makers Modern Cooking carries, Fredrik Spåre, Brook Turner, and Jesse Thompson work in 52100. Note that it is the same alloy as German 1.3505 and the European 100Cr6; if a maker tells you they have used one, they have used all three.

Also known as:1.3505, 100Cr6

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

Flat

A grind in which the blade tapers in a straight line from the spine down toward the edge, with no curve or hollow in the bevel. The flat grind is the most common geometry on modern double-bevel kitchen knives because it balances cutting performance and durability: thin enough behind the edge to slice well, with enough steel behind it to stay strong.

A true full flat grind, running from spine to edge, is keen but can wedge in dense produce as the food meets the widening blade; many kitchen knives use a partial flat grind that begins lower on the blade to manage that. The flat grind's appeal is its predictability — it sharpens straightforwardly, behaves consistently, and asks nothing unusual of the user.

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.
