The Mk.1 Gyuto represents the beginning of a new range of knives from Adonis Forged Arts with blacksmith Antoine Kniamen producing limited edition small batches. This first batch sold out very quickly with a single piece being made available to Modern Cooking along with this one of a kind "Spicy Edition".

The first series featured German tungsten alloyed 1.2442 core steel, but this "Spicy Edition" has been forged in TNT666. TNT666 is an extremely wear-resistant alloy tool steel with a high harden-ability and great wear resistance. A rare steel with exceptional performance.

The profile is a variation on his classic pointed Gyuto profile with a slightly more gentle, relieved heel design, classic subtle radius edge profile and fine convex bevels.

A mono steel construction with a touch of brute de forge, a spicy red acrylic handle with a wood grain "mokuton" textured brass heirloom fit bolster. 

Celebrating an exceptional release from Adonis Forged Arts with a striking kitchen slayer. This Spicy Edition Mk.1 Gyuto with upgraded steel is a standout addition to this inaugural batch of top end knives.

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.

Origin
Germany (specialty mill; associated with the European custom maker community, including Adonis Forged Arts)

TNT666 is a German specialty carbon steel built around roughly 1.15 percent carbon and three deliberate alloying additions at 0.6 percent each — tungsten, niobium, and titanium — from which the "666" name derives. The chemistry is engineered for extremely fine carbide formation: niobium and titanium produce small, hard carbides that resist abrasion without coarsening the grain, and the tungsten supplies conventional wear resistance.

In editorial terms, TNT666 is positioned as a "fine-grain Aogami #1 plus carbides" — a clean, high-carbon Western answer to the blue papers, with the micro-alloyed additions contributing to a noticeably refined apex. Hardness in finished knives runs 63–66 HRC; edge retention is meaningfully better than Aogami #1, and sharpening behaviour stays close to that of a clean carbon despite the carbide load.

Among the makers Modern Cooking carries, Adonis Forged Arts works in TNT666. Outside the catalogue it is found in a small number of related German custom shops. It is genuinely a niche enthusiast's steel.

Blade construction

Mono Steel

A knife forged from a single piece of steel — no laminations, no clad layers. The simplest and most direct construction. The entire blade is the cutting steel, with no softer outer jacket to protect or contrast it. Most contemporary Western kitchen knives in carbon and stainless steel are mono-steel constructions, as are honyaki and most European bladesmith work.

The trade-off is straightforward: mono-steel knives are easier to forge, sharpen, and reason about, but the entire blade carries the cutting steel's properties — including its reactivity if it's a clean carbon. There is no soft jacket to protect a more brittle core from impact, so the heat treatment and geometry have to do all the work.

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.
