Hitachi HAP-40 is currently one of the most mysterious and attractive steels produced in Japan. This hi-tech powdered metal steel alloy has a very rich chemical position and, when it is forged and heat-treated properly, we believe that it probably offers better cutting performance and edge retention than any other high-quality Japanese steel.
Sukenari’s knowledge of traditional forging processes and their extensive experience with modern, high performance, steels proved to be invaluable while perfecting these new HAP-40 knives. Master Hanaki, Sukenari’s innovative and energetic knife maker and Master forge-smith, has successfully managed to extract the best cutting performance and edge retention from these HAP-40 knives (HRc. 68). They are perfect for customers who love testing exotic hi-tech steels, or those who appreciate knives with outstanding cutting performance and edge retention.
Master Hanaki believes that these new HAP-40 knives offer very competitive cutting performance and edge retention relative to his ZDP-189 and Aogami Super knives. In addition, HAP-40 offers better toughness than ZDP-189, - even when it is heat-treated to a higher Rockwell hardness. Consequently, Master Hanaki has confidence that the new Sukenari HAP-40 knives will prove to be some of the best performing and most practical knives that Sukenari offer.
Sukenari HAP-40 knives are fitted with a ellegant and classic octagonal Ebonywood handle, which has a buffalo horn ferrule. For safekeeping, this knife comes with a matching Black Lacquered wood Saya (Sheath) with a black pakkawood Saya pin.
The Gyuto is the Japanese version of the classic Western Chef’s knife. It can be used with a variety of different cutting techniques to achieve a wide range of kitchen tasks and is suitable for cutting the vast majority of meats, fish, vegetables and fruits. The Gyuto is true multi-purpose knife. Compared to a Western-style handle, the lightweight traditional Japanese handle of the Wa Gyuto knife moves the balance point of the knife further towards the tip, which makes it feel more nimble and precise.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.
For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems.
We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy the fine craftsmanship and its sharp edge of your new knife. With proper cares, every Japanese knife should be your special cooking partner for a long time.
This is the Powdered High Speed Tool Steel blade kitchen knife that has a rust resistance for easy maintenance. However, it may get rust, if kept in wet condition.
Of all the super knife steels, this was the only one I didn't have and decided to pick up one of these. This now is one of my top 2 knives that I use on a regular basis, came razor sharp, holds a great edge and cuts like a dream. Plus Sukenari's fit and finish are second to none and JCK takes good care of their customers! Love this knife!
Not too bad to sharpen and stays sharp for a while
