Simon Mailet

Sheffield, England · High Performance, Handcrafted Kitchen Knives

Simon Maillet

Simon Maillet approaches kitchen knives with the practical instincts of a former professional chef and the discipline of a highly skilled craftsman. Working within Sheffield's historic steelmaking culture, he produces clean, understated knives shaped through Japanese grinding and whetstone-finishing techniques. The collection is focused, restrained, and highly usable, favouring consistency, maintainability, and cutting feel over visual excess.

About the maker

On the workshop

Simon Maillet came to knife making after many years as a professional chef, a path shared by a number of the most thoughtful contemporary makers. Born in France, he moved to England in 2017 and was soon drawn to Sheffield, the historic home of British steel working. The city's long association with cutlery and edge tools gave him both context and community for the practice he was building. Sheffield is where the workshop now sits, and where Simon has developed a quietly serious reputation, first among British chefs and now with a steadily growing international audience.

His philosophy is unambiguously pragmatic. The knives are tools first, intended to be used, sharpened, and maintained over long working lives rather than admired in a display case. Much of his approach draws on traditional Japanese methods: blades are ground on a water wheel and finished on whetstones, producing very flat and consistent bevels that respond predictably to maintenance. The aesthetic that results is elegant but minimal — clean profiles, restrained finishing, no unnecessary decoration. Beneath the surface, the work rests on a careful bedrock of process, the kind of detail that is hard to see but easy to feel in the hand.

For years Simon was something of a well-kept secret, with much of his work going quietly to British chefs through word of mouth. International collectors and cooks have since taken notice, and his knives now travel well beyond the UK. The combination of chef's-eye function, Sheffield setting, and Japanese-influenced grinding gives the work a clear identity that does not need ornament to make its case. We are proud to present Simon Maillet within the Modern Cooking Collectors Selection, where his refined restraint and tool-first discipline speak directly to the cooks and chefs at the centre of our audience.

Signature construction

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.

Cutting edge steel

135Cr3

Plain high-carbon tool steel

Typical HRC
62–65
Corrosion class
Carbon
Production
Conventional
Origin
AFNOR / DIN; closely overlaps 1.2008

Editorial note: despite the "Cr3" suffix, which superficially suggests a low-carbon case-hardening grade, 135Cr3 is in fact a through-hardening high-carbon tool steel. The name is occasionally a source of confusion when buyers see the steel listed in older catalogues alongside true case-hardening grades like 16MnCr5; in practice 135Cr3 is interchangeable with 1.2008 for kitchen knife purposes.

The editorial profile follows 1.2008: a respectable, traditional European high-carbon at 62–65 HRC, with moderate edge retention, good toughness for the hardness, and conventional patina behaviour. It is most often seen in French and German workshop production where the carbon-steel idiom is part of the maker's identity. Among the makers Modern Cooking carries, Yanick Puig, Milan Gravier, Guirec Péron, and Jonas Johnsson work in 135Cr3.

Also known as:1.2008

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.
