A beautiful classic Mizu Honyaki with full mirror polish from French blacksmith Guirec Péron. The blade, forged in 135Cr3 steel, is ground convex and features a lovely gentle taper. A clean set of consistent convex bevels give this undoubtedly premium cutting performance and the classic Gyuto profile with its gentle radius is a seriously smooth operator on the cutting board.

Guirec's knives exhibit lovely aesthetics delivered with finesse. The shape of the blade has a classic yet iconic and individual form that delivers in terms of performance, while also having a captivating and striking style to it. The mirror polish gives the blade a delicate sensibility that is somehow quite rare in contemporary knife making. But let’s not overlook what makes a Honyaki, a Honyaki, that beautiful Hamon. On this knife its beautiful, subtle cloudy haze with complex contrasting characters that stand out in a lovely way on the mirror polished steel. The handle is a signature shaped hidden tang handle in burnt walnut. It’s a simple and yet very elegant combination.  

Every detail of this blade has been beautifully finished with care and finesse. Honyaki kitchen knives are some of the most challenging to forge and Mizu Honyaki are to most challenging, but the water quench pushes the toughness of the steel to its limits. It takes patience, diligence, and heart to produce knives like this. A stunning piece of work from Guirec Péron.

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

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

Honyaki

The traditional Japanese single-steel forging technique, in which a high-carbon mono-steel blade is differentially hardened — clay is applied to the spine before quench, leaving only the edge to fully harden. The result is a hard cutting edge and a softer spine that improves toughness, plus the hamon (temper line) that defines the visual signature of the technique.

Honyaki is the high-water mark of Japanese knifemaking. The technique is unforgiving; a failed differential quench cracks the blade. Honyaki knives are almost always from a single high-purity carbon steel — Shirogami #1 is the canonical choice — and are priced and treated accordingly.

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.
