Gyuto 215mm 125sc Honyaki Linear Texture Hamon - Ukraine Fundraising Auction


This Karol Karyś Gyuto was aucitoned off on our Instagram account to raise money for children who have been harmed or displaced as a result of the conflict in the Ukraine.

The linear texture on this Karol Karyś Gyuto 215mm was discovered on the streets of Kraków an example of Karol's passion for the brutalist design that is present in all of his knives. This piece has been produced by Karol to raise money to support Ukrainian children who have been affected or harmed as a result of the war in the Ukraine. All proceeds from the sale of this knife will be donated to the Voices of Children Charitable Foundation.

This 215mm Gyuto features a differentially hardened (Honyaki) blade with a "Linear" textured hamon. The result is a stunning array of contrasting textures and shades of grey and black. Karol's Gyuto profile features an oversized honesuke style shape with a very large flat section extending from the heel about two thirds of the length of the blade before gradually curving up towards the tip. This profile will excel at chopping and slicing.

The blade extends out of a bespoke burgundy and forest green dyed and stabilised maple handle, which is paired with a uniquely textured bolster, in this case it’s a brass bolster with a pitted texture, reminiscent of raw concrete and another example of the brutalist design that inspires these knives.

Stunning to behold, the knife performs beautifully in every way. A very thin and perfectly convexed blade. Highly polished and perfectly finished. An undeniably beautiful knife for an undeniably good cause.

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.
