Gyuto 215mm Honyaki Kogatana Set


Joel Black has polished and etched to revel a stunning hamon and incredible alloy banding on this honyaki kogatana set. If you have ever wondered how this kind of finish is achieved, it’s a long process of skilfully polishing the steel on a variety of specialty whetstones, some of which are very rare and often extremely expensive. The steel is also etched in various contrast solutions like citric acid, which highlight the hamon and alloy banding.

Joel has a passion for this kind of finish, and it shows in the results, which are stunning. 

From a performance perspective the edge is very sharp, and geometry is beautifully shaped. Perhaps one of the best features of a stone finished knife like this is that it’s very difficult to achieve such a clean and beautiful finish while also hiding inconsistencies in the bevels. So, what you get is perfect bevels that are easy to maintain and a geometry that is a pleasure to cut with.

This is one of two honyaki kogatana sets that we recently received from Joel, both have walnut, dear antler, and buffalo horn handles and walnut sayas. Both knives also feature a kogatana utility knife as part of the package, which is also finish in the honyaki style.

This is a stunning piece of work from Joel, the kind of thing we would happily take home ourselves.

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.
