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 unique natural wooden texture of octagonal Bocote wood handle, which has a buffalo horn ferrule. For safekeeping, this knife comes with a matching Black Lacquered Wooden Saya (Sheath) with a black pakkawood Saya pin.
The long, narrow, graceful blade of the Sujihiki is particularly useful for trimming away sinew and fat from meat, finely slicing meat or boneless fish, or for filleting and skinning fish. The long blade allows the meat or fish to be cut in one single drawing motion, from heel to tip.

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.
Superb knife, one of the sharpest out of the box knives I’ve owned. Slices super fine, even with prosciutto or other sticky foods. It is important to note that the thinnest of the blade coupled with the hardness of the steel, one must be careful not to misuse the blade. Bottomline: I really like this blade and it has become one of my favorites!!!
Cuts like a razor, Made fast work of finely sliced Yellow fin tuna!. Pleasure to use!.
