First Impressions

The immediately notable feature of the entire Kotetsu range is just how thin the blade is, in our sharpness tests we found it rated right up there with the best we stock and due to this much thinner construction it's also very noticeable how light the knife is as a whole.

Beauty

A dark brown and black octagonal rosewood handle in a traditional style combined with the clean, laminated finish of the blade gives a lovely contrast. The steeper, straight edge at the end of the blade instead of a more traditional rounded style creates a unique look.

The name "Iron clad" doesn't refer to the metals used in the making of the knives, they're powder steels not iron - but instead refers to the shape of the knives which is inspired by Japan's first iron clad battleships (Kōtetsu).

In Hand

We felt immediately that the lightness of the knife would be a big benefit for those who don't like the more Western style and it was extremely comfortable to use for extended periods.

Durability

The powdered steel used in the blade construction will keep an edge for a long time although due to the very thin blade construction we think this knife might be best suited to someone who has a more careful and considered cutting technique to avoid micro-chips appearing although we found no big issues with it while chopping through a range of veg and meat.

Ease of Care

The usual care instructions of not putting in the dishwasher apply of course and we found a quick rinse and dry after use and you'll have no problems at all.

Our Verdict

The high quality blade and handle perform well and combined look the part without breaking the bank. If you're looking for performance at a very reasonable price then the Kotetsu is for you.

Over the last few years, knives from the Koutetsu ranges have become quite collectable due to the scarcity of the supply and its excellent performance and price point.

Our aim is to measure and photograph our products as accurately as possible but due to many items being handmade, finished or using natural materials, there can be minor variance in measurements and things such as blade or wood finishes can vary. We will always endeavour to provide the most accurate measurements, photos and descriptions of our products.

Some measurements such as HRC are provided by manufacturers and should therefore be used as a guide.
