Chef Knife 230mm "THRN" GoMai Cast Aluminium & Amethyst


Karol Karyś has developed his reputation around a unique design style, but his knives have always featured very good cutting performance. This unique one-of-a-kind chef knife takes things to a new level though. A subtle radius at the edge results in a delightfully cutting action on the board. Its just smooth and easy with a tapered, convex geometry that will make short with of root vegetables, while the laser thin tip easily pierces and slices more delicate skinned produce. Beautifully balanced and nimble in the hand, yet satisfyingly weighted. This is certainly a performance piece, but…

Let’s get to the looks.

The blade is forged from a house laminated GoMai billet. At the core 1.2419 German tool steel, it’s a fantastic steel and holds a sensational edge. The cladding is a low layer Damascus with a nickel diffusion layer. Karol has etched the blade pitch black, and it is filled with dark contrasting layers blending into textural elements around the pinch point. The textures transition into the handle, and this is where Karol has really let himself go. 

The handle is an incredible piece of artistry and craftsmanship. We have seen milled aluminum handles in the past, but this is not so simply. The handle was cast on this piece. An exacting shape needed to be constructed to support the two thorns (THRN) or amethyst stones, which have been set into the butt of the handle. So, first a form was constructed with the two purple stones set in place. The aluminum was poured and cast. The two halves of the handle have been fixed in place with hidden pins. Karol has finished the knife with an assortment of thoughtfully placed and considered textures, which give the knife his signature look and feel, but this is certainly something of an exceptional piece. 

There is an irony to the knifes name THRN pronounced thorn! Yes it has thorny looks, but when gripped in a pinch the thorny stones sit well behind your hand and it’s a comfortable ergonomic and well balanced knife.

As with many of the knives found in the Modern Cooking Auction section this is functional art or as we like to refer to it, epicurean art! This piece is a luxurious indulgence that is sure to bring you a sense of satisfaction and joy when you enter your kitchen.

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.
