Shirogami Nr. 1, verkleidet mit altem Schmiedeeisen, vollendet mit einem rustikalen schwarzen Kurouchi und einer schönen trüben Kasumi-Politur. Die geschmiedete Geometrie von Simon ist sehr beeindruckend, flache, flach geschliffene Fasen, wobei sich die Klinge zum Rücken hin verjüngt, um eine verbesserte Schneidleistung zu erzielen. Premium-Passform und -Finish bleiben der Fokus mit einer Schönheit, die mehr als nur oberflächlich ist.

Die Klinge aus Shirogami-Stahl Nr. 1 ist ein reiner Stahl mit erstaunlichen Kantenqualitäten und wird auf einem Wasserrad geschliffen, um eine konsistente, leicht zu wartende flache Primärfase zu erzielen. Super dünn hinter der Schneide, das Messer schneidet schön. Ein klassisches Gyuto-Profil mit Santoku-Spitze und feiner Kantengeometrie, das sich bequem durch die Produkte bewegt, ohne sich zu verkeilen oder zu quetschen.

Ein alter Eichen- und schwarzer Büffelgriff in Simons maßgeschneiderter achteckiger Form mit übergroßer Zwinge vervollständigt das Messer. Einzigartig und ergonomisch mit subtiler, klingenfokussierter Schönheit.

Wenn Sie auf dem Markt nach einem neuen Gyuto Simon suchen, bietet die Arbeit von Gyuto Simon Qualität und Schneidleistung weit über ihrem Preis und einige sehr coole Looks.

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

Shirogami #1

Ultra-pure plain carbon steel

Typical HRC
64–67
Corrosion class
Carbon
Production
Conventional
Origin
Japan (Hitachi YSS / Proterial)

Shirogami #1 — White Paper #1 — is the highest-carbon, highest-purity entry in Hitachi's white-paper family, with approximately 1.30 to 1.40 percent carbon and impurities (P, S, Mn, Si) held to extremely low levels. Without chromium, tungsten, or vanadium, it is the closest thing the modern industrial world has to a continuation of the traditional Japanese tamahagane lineage in commercial form.

In a finished kitchen knife it can run at 64–66 HRC, sharpens to an extraordinary apex on natural and fine synthetic stones, and gives a feel at the cutting board that aficionados describe as glassy. Edge retention is modest — the absence of carbide-forming alloys means the steel is wear-limited — and toughness at this hardness is genuinely low; a thin Shirogami #1 edge will chip on bone or on a poor cutting board. The patina is energetic.

It is the steel of choice for honyaki and high-end clad single-bevels, and it remains the touchstone against which other ultra-clean carbons like 125SC and C130 are judged. Among the makers Modern Cooking carries, Hado Knives and Simon Maillet work in Shirogami #1. Recommend it only to a cook who understands what it is asking of them.

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.
