Designed by renowned sharpener Takayuki Shibata, the Koutetsu "Type 3" Aogami Super (AS) series is the result of a pursuit for cutting perfection. With a unique silhouette inspired by the straight lines of historic Japanese warships, this knife glides effortlessly through ingredients thanks to its ultra-thin grind and carefully considered geometry. For best results, use with clean technique and avoid cutting through hard materials like bone or frozen food.

At its core is Aogami Super - a carbon steel known for its outstanding sharpness and edge retention. This is sandwiched in a stainless steel cladding, offering a great balance of cutting performance and reduced maintenance. Like all reactive steels, it will develop a patina and must be dried thoroughly after each use.

What sets the Koutetsu apart is its exceptional fit and finish. The spine and heel are rounded for comfort, and its brushed finish with engraved kanji delivers understated elegance. A traditional rosewood octagonal handle with pakkawood ferrule keeps the knife lightweight and balanced.

Highly collectable and often hard to find, the Koutetsu AS is a favorite among professionals and serious home cooks alike. It’s sharp out of the box, easy to control, and a joy to use - designed to last for years with proper care.

Note: As with all carbon steel knives, the core steel is reactive. Be sure to clean and dry the blade after each use to prevent rust.
