AUCTION - Gyuto 270mm Full Mirror Polish Honyaki C105-W1 Integral Oosik & Ebony


This product is unavailable

A Gyuto 270mm forged in C105 or W1 steel, an amazingly thin and sharp blade with a high performance walkschliff grind and tapered spine. The hamon is an incredible subtle, hazy, wave pattern that streaks across the top of the blade and compliments the beautiful mirror polish perfectly. This is one of the finest honyaki blades we have had the privilege of seeing.

A perfect mirror, to create such a thing means hours of work just for this one detail. From a blackened piece of steel covered in forging scale the blade must be profiled, and ground clean, the bevels and walkschliff cutting geometry must be applied, then finally the artisan works by hand, sanding and polishing until every scratch is blended and the steel becomes the beautiful mirror you see here. This is just part of the work that has gone into creating this masterpiece from artisan blacksmith Jonas Johnsson aka Isasmedjan.

Extending back from the forged integral bolster is an incredible, extraordinary Oosik and ebony handle. The blue, green and yellow hues of the speckled material are a striking, textural pairing with the smooth as silk mirror blade and the luxurious dark ebony spacer that traverses the middle of the handle provides a beautiful piece of contrast.

This is a once in a year piece for Swedish artisan blacksmith Jonas Johnson, with hours of work invested in the forging and polishing of the blade, and incredibly rare and beautiful materials for the handle. A stunning center piece in any collection.

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. 

A reference guide to steel types

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.
