Bunka 135mm OB Go Mai Micarta & Copper


This product is unavailable

Karol Karyś is a consistent innovator, unique designer, and extremely talented craftsman. Continuing with our Oblivion Blades collaboration, Karol has taken things in a new direction with this 135mm Bunka. The blade features a unique fluted “S” grind, giving the brutalist textures a pragmatic touch and adding purpose to the signature made by Karyś detail.

The blade features a nice subtle curve from heel to tip. The unique fluted “S” grind is very thin behind the razor-sharp edge. This fun little bunka would be great for light prep work and the perfect knife to set at the table with hard cheese, dried sausage, and cold drinks.

Completed with the classic made by Karyś facetted handle and textured copper bolster.

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.
