Gyuto 244mm Mizu-Honyaki Mirror


A beautiful classic Mizu Honyaki with full mirror polish from French blacksmith Guirec Péron. The blade, forged in 135Cr3 steel, is ground convex and features a lovely gentle taper. A clean set of consistent convex bevels give this undoubtedly premium cutting performance and the classic Gyuto profile with its gentle radius is a seriously smooth operator on the cutting board.

Guirec's knives exhibit lovely aesthetics delivered with finesse. The shape of the blade has a classic yet iconic and individual form that delivers in terms of performance, while also having a captivating and striking style to it. The mirror polish gives the blade a delicate sensibility that is somehow quite rare in contemporary knife making. But let’s not overlook what makes a Honyaki, a Honyaki, that beautiful Hamon. On this knife its beautiful, subtle cloudy haze with complex contrasting characters that stand out in a lovely way on the mirror polished steel. The handle is a signature shaped hidden tang handle in burnt walnut. It’s a simple and yet very elegant combination.  

Every detail of this blade has been beautifully finished with care and finesse. Honyaki kitchen knives are some of the most challenging to forge and Mizu Honyaki are to most challenging, but the water quench pushes the toughness of the steel to its limits. It takes patience, diligence, and heart to produce knives like this. A stunning piece of work from Guirec Péron.

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.
