Patina Nakiri Knife | The "Platypus" Knife | G10 Handle


Introducing Koi Patina Knives. Designed for the professional kitchen, we have taken some of our favourite designs and reinforced them with G10 handles and forced patina finish. This improves their wear resistance, allowing the knives to take on some of the brutal challenges a commercial kitchen has in store.

The Platypus Knife takes its design from the Japanese Nakiri, designed for vegetable chopping. Its flatter belly allows it to make full contact with the board after every cut; perfect for fibrous vegetables and soft herbs. Now with the industrial treatment, it is a compact blade with plenty of control.


Blade Length: 150mm (6") | Over All Length: 292mm (11.5") | Blade Thickness: 3mm (0.118") | Weight: 275g (9.70oz) | HRC: 60-62

VG10 high carbon Japanese steel construction with forced patina acid wash.

The high carbon content core ensures a razor-sharp cutting edge, clad with stainless steel for protection. We have opted for a forced patina finish where the knife will develop character over its lifetime, but will maintain its corrosion resistance.

G10 is a heavy duty composite material made from a fibreglass and resin laminate. It is used in tactical applications in the military like pistol grips and knife handles because of its hardwearing properties and indestructibility. It is a fantastic material for kitchen knives, where the feel and finish provides good grip even when wet or oily.

We produce durable, high-quality knives and products for both culinary and utility use.
