The Gyuto 240mm Honyaki - Brute de Forge with stacked birch bark is perhaps a little familiar as a similar piece was featured in Blade Magazine last year. The silky smooth mirror finish with the subtle touch of brute de forge above the Hamon is a very classy look.

Performance wise the blade features 64+HRC 26c3 "Spicy White" steel, Jonas's pointed Gyuto profile and very nicely finished walkschliff grind. For those unfamiliar with the walkschliff its basically convex plus, we have written a little about it in a recent post. Jonas has done an amazing job on these grinds and you will certainly find that they perform beautifully well on the board. Nice distal taper, super thin edge and delightfully balance result in one of the best made knives around.

A signature stacked birch bark handle completes this heirloom piece from Jonas.

Blade type

Gyuto

牛刀

The gyuto is the Japanese interpretation of the western chef knife, and the most versatile blade in a modern kitchen. It carries a long edge, most often 210 to 270 mm, that runs flatter through the heel than its western counterpart before rising in a gentle, late curve to a fine point — a line that favours push- and pull-cutting while still allowing a rocking motion when the work calls for it. There is enough height at the heel to keep knuckles clear of the board, and the tip is fine enough for detail work, which is why most cooks reach for it first.

The flatter edge is the defining characteristic and the trade-off both. More of the blade lands on the board at once, which suits push cutting and gives clean, decisive contact through an ingredient, but a cook who works primarily by rocking will find less curve to work with than a western profile offers. Modern makers increasingly blur the line between the two, drawing a profile that rocks and push-cuts equally well — Birch & Bevel's Modern Gyuto profile, Antoine Kniamen's Western Gyuto, and Benjamin Kamon's own gyuto profile are all examples of that hybrid thinking.

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

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

Walkschliff

The Kesselscher Walkschliff is a traditional Solingen grind in which each face of the blade curves outward from the spine, reaching its greatest thickness slightly below it before tapering towards the edge. Beneath this pronounced convex “bulge,” the blade is ground exceptionally thin and continues into a fine, subtly convex cutting edge. This distributes material through the upper blade for rigidity and stability while preserving the low cutting resistance of a very thin edge.

Achieving this compound geometry consistently demands considerable control, specialist knowledge and experience, whether it is produced on a traditional grinding wheel or with a belt grinder. Once part of Solingen’s celebrated grinding tradition, the Walkschliff is now practised by relatively few makers. A well-executed example is valued for the way it reconciles qualities that can otherwise seem opposed: strength through the body of the blade, fineness behind the edge and an exceptionally keen, confident cut.

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.
