Something a little different from Jonas Johnsson this time. A little while back we managed to import some Aogami #2 steel from Japan, which we immediately knew to send to Jonas. Aogami #2 is a great steel for Honyaki blades and so who is better suited than Jonas Johnsson, Europe’s preeminent Honyaki master.

The results are in, and this is one classy looking blade with incredible geometry to match. A thin laser geometry with a profile reminiscent of the Yoshikane SKD Gyuto. Walkschliff ground, this blade is going to feel like the Yoshikane on the board, but perform much better.

A unique integral bolster with an ergonomic dimple, which transitions into the handle. The knife feels amazing in the hand, nimble, well balanced, just a very fine piece of work. The handle is made from a beautifully figured piece of Macassar ebony, which features an amazing array of red and brown hues.

Jonas has an amazing sense for the aesthetics, allowing this clean, highly polished blade to sit simply next to the stunning Macassar ebony. Nothing complicated, just a beautifully forged Honyaki blade with a stunning mirror polish and an incredible piece of timber. Both pieces treated as they should be and allowed to shine. A timeless piece, beautiful!

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

Aogami #2

High-carbon tungsten-chromium steel

Typical HRC
61–64
Corrosion class
Carbon
Production
Conventional
Origin
Japan (Hitachi YSS / Proterial)

Aogami #2 — Blue Paper #2 — is the most widely encountered of the blue-paper steels and the one most cooks meet first. About 1.10 percent carbon plus half a percent each of chromium and tungsten is enough to noticeably extend edge retention over the white papers without dramatically changing how the steel feels at the stone.

In a typical clad gyuto or santoku the steel runs at 61–63 HRC, sharpens cleanly on most synthetic stones, and produces a reliable, hard-wearing edge. Toughness is good for the hardness — the lower carbon content compared to Blue #1 helps here — and the patina develops at a moderate, manageable pace. It is genuinely a workhorse: forgiving of slightly imperfect technique, tolerant of a wider range of foods, and broadly available across price points.

Among makers, Aogami #2 is the default blue paper for everyday clad knives, found across the bulk of the Sakai and Tosa traditions' working-cook offerings. Among the makers Modern Cooking carries, Katsushige Anryu and Jonas Johnsson work in Aogami #2. It is perhaps the steel that best illustrates Hitachi's philosophy: clean composition, predictable behaviour, ample room for the smith to leave a fingerprint.

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

A traditional Solingen grind — also called a kettle or kessel bulge grind — in which the blade is hollowed high on the side so its thickest point sits a little below the spine rather than at it. Below that bulge the steel is taken down to an extremely thin, finely convexed cutting edge, combining the rigidity of a thick upper blade with the keenness of a very thin one.

The Walkschliff is among the most demanding grinds to execute, historically reserved for the finest German knives and requiring years of a grinder's experience to do well. For the buyer it is a high-craft European alternative to the thin flat grinds of Japanese knives — strong, stable, and keen — but it is a hand-ground specialism, and a knife that carries it is priced for the skill it took to make.

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.
