Gyuto 230mm Mono Integral Take Down

$1,797.00

The 230mm Gyuto, forged from 1.3505 German Tool steel, represents the pinnacle of functional knife design by renowned German blacksmith Oliver Märtens of oel knives. Forged in his Kassel, Germany studio, this knife embodies Märtens’ signature design language, which is rooted in clean, deliberate lines and a focus on purpose-driven functionality. Influenced by the principles of the Bauhaus movement, Märtens integrates structural clarity and minimalist efficiency into every element of his work, ensuring that the form of the knife serves its practical role with precision.

The blade features a bold and performance-focused gyuto profile with wide convex bevels, providing an optimal balance between cutting power and precision. Its tapered spine enhances maneuverability, giving the knife a nimble and balanced feel in the hand. The ergonomic design ensures comfort and control, making it suitable for long hours of use in demanding kitchen environments. The focus on functionality and balance reflects Oliver’s commitment to creating tools that perform exceptionally well while feeling intuitive and responsive during use.

This Gyuto also showcases Oliver’s innovative take-down handle design, which allows for easy disassembly and maintenance without compromising structural integrity. You can learn more about this practical feature in this video on takedown handles. The handle itself combines a forged integral bolster with an anodized aluminum body and a custom brass rear end cap, secured with a titanium locking screw for durability. Märtens’ design philosophy is evident in every detail, delivering a knife that excels in cutting performance, ergonomic precision, and purposeful construction.

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.
