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 handcrafted Magnolia wood Saya (Sheath) with a black pakkawood Saya pin.
The lightweight, double bevel edged Kiritsuke might be compared to a combination of the Nakiri and the Sujihiki. It is a very versatile knife that can be used to perform many of the tasks normally done with a Gyuto.

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.
This knife had the best edge you could ever want right out of the box. It was delivered very quickly and had great balance in my hand. Amazing kitchen tool !!!
I can just say amazing. This is my third knife from Sukenari. It feels like it doesn't won't get dull. Well balanced. Great job on handle. It is my daily to go knife in busy kitchen and it is always pleasure to start my day with this guy. Big thanks Sukenari and JCK for superb service and customer support.
Ever wonder why Sukenari knives are almost always listed as "Sold Out" on websites geared to high-end chef's knives? The key is their intriguing marriage of that subtle mystery and mystique alive in the blades of exalted Japanese Chef's knives. Certainly, the specs speak for themselves, but, above and beyond, this knife happily sings out of its saya, making you wish for an involved ratatouille recipe, whose "mis en place" will keep you gleefully at the cutting board for a few hours of total bliss, while experiencing the beauty of how this knife deftly purrs through your produce, leaving pristine, mirror polish cuts. Its pleasurable heft and an exacted balance point will make you more than smile. If you can even get one, don't start soaking your stones once it arrives – resist the sharpening urge. Use it and get to know it after you begin cherishing its veritable, artful mastery, only after that very first slice.
