Adonis Mk.1 Gyuto Spicy Edition TNT 666


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.

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 one of the many premium reactive German and Swedish steels are susceptible to rust if not properly cared for. In this case we advise that you keep the knife dry between uses and when storing the knife for longer periods wiping the knife blade with Tsubaki oil or another food safe oil is a wise choice. This will not stop a patina forming on the blade, but it will stop rust. A patina can be a beautiful personal feature on your knife and helps to stop rust forming. So, dry your knife regularly between uses, store in a dry place and apply some Tsubaki oil from time to time when storing for long periods.

Handle Care: If you have a knife with a non-stabilised wooden handle, you can apply Tsubaki oil or another food safe oil to your handle from time to time. Food safe wax can be applied to both stabilised and no-stabilised wooden handles. Never apply hot wax or oil as you risk warping or damaging the handle.
