The ajikiri is a specialized Japanese knife engineered for processing small fish with precision. Its name comes from “aji” (horse mackerel) and “kiri” (cutting), highlighting its purpose as a tool specifically designed for cutting aji and similar fish. Featuring a short, robust blade (typically 90–120 mm) and a pointed tip, it excels at fine tasks such as filleting, gutting, and deboning species like horse mackerel and sardines. The knife has a single-bevel edge, making it ideal for right-handed users who require highly accurate cuts close to the bone. This design makes the ajikiri an essential tool for detailed fish work in both home and professional kitchens. Mr. Hiroo Itou knives barely needs an introduction, his knives are works of art. All Mr. Itou’s knives are completely handmade and unique. Famous for their exquisite and colourful handles, these knives are made with SG2 (R2) powdered steel in the core to ensure not only a sharp but easy to sharpen knife edge (Rockwell hardness HRC 62). These knives are one off pieces and not easy to get hold of, we cannot guarantee a stock at all times.

Mr Itou and Mr Nagata now make these knives together and they will now be known as Mr Itou (Yusui) knives.

All Kin Knives come with a lifetime guarantee as long as they are treated correctly in accordance with our care instructions.
