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.
The HAP-40 core blade steel (HRc. 68) is forge-welded with Stainless Damascus steel cladding, which is made with alternating layers of Nickel Steel and Stainless Steel. The blade is beautifully mirror polished and finished so that the white color of Nickel Steel layers vividly contrast with the glossy silver color of the Stainless Steel layers.
Sukenari HAP-40 knives are fitted with a beautiful octagonal Ebony wood handle, which has a buffalo horn ferrule and White Spacer. A Magnolia wood Saya(Sheath) is also included with the knife for safekeeping.
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.
I ve bought the knife cause I know the sukenari knives and I think their shirogami yanagiba honkasumi knifes are one of the best i ve ever seen, then i bought this HAP 40 sujihiki cause i know this powdered steel, but what should i say? This knife is really impressive nice handle 4/5 -impressive steel 5/5 with nice sharpeness out of the box -3/5 Ok the price is not impressive but it is worth. Sharpening is for powdered steel a little bit difficult is you not using shapton or imanishi stones but in combination with shapton and some natural polishing stones the sharpeness is really good -for powdered steel-
Handles like a dream and holds a razor sharp edge. Koki carries the best products and the service is second to none.
Great quality knife, razor sharp, like all your products and super quick shipping. Japan to New Zealand in 5 days!! I'd definitely recommend this knife, if still available, or any other Sukenari!
