Gyuto 245mm GoMai Apex Ultra


Crafted by the skilled hands of Tobias Hangler, this one-of-a-kind piece is a high performance cutting tool from every angle.

With an impressively thin and sharp 245mm edge length, it has been meticulously forged from in-house Go Mai steel. Enveloping Tobias's proprietary Apex Ultra steel core is 80CrV and nickel. The core is hardened to 66HRC for a very acute and razor sharp edge. The premium Apex Ultra steel has a beautiful, refined grain structure that gives the knife amazing toughness and edge retention.

The spine measurements reveal a calibrated taper, ensuring effortless cutting from heel to tip. Weighing 240g, it offers a harmonious blend of satisfying weight and balanced manoeuvrability. Convex ground for a balance between precise, effortless cuts and good food release.

The 5-layer Go Mai has been acid-etched, and satin-polished giving the blade a beautiful and unique aesthetic. 

Craftsmanship extends to the handle, meticulously constructed from Bog Oak and Elforyn for an exceptional grip and aesthetics. The hidden tang construction ensures both comfort and balance for ambidextrous use.

Tobias's Gyuto 245mm is more than a knife; it's a true work of culinary artistry. Whether you're a professional chef or a passionate home cook, this Gyuto promises an unparalleled experience, fusing design and functionality into a seamless culinary journey.

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.
