This is the Custom Limited Edition and result of Collaborative works with Custom Handle Maker for making one of a kinds, Custom Limited Edition Sukenari HAP-40 Clad Wa Sujihiki knife.
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.
This Custom Limited Edition Sukenari HAP-40 Clad Wa Santoku knife is fitted with an Custom Hand-Made Octagonal Handle(Resin body, ferrule and endcap with G10, Brass and Copper spacers).
For safekeeping, this knife comes with a matching Black (Lacquered) Wooden Saya ("Sheath") and a black pakkawood Saya pin.
This knife comes packaged in an elegant wooden presentation box that is secured with woven fabric ties / straps.
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.
Okay, that might be an exaggeration, but HAP-40 is next level for anyone not familiar. The description above of HAP-40 edge retension and hardness doesn't do the knife justice, it is almost unbelievable. Anyone concerned about maintaining such a hard steel need not be, regularly maintaining the blade with a simple steel or ultra-fine stone allows for much longer intervals between laborious sharpening sessions than any other knife I own. I apply a small amount of food-safe mineral oil to the edge of the blade to stop any discolouration (as you can do with any high-carbon knife) but a simple baking soda solution will clean away any patina that appears. The knife balances at the most forward portion of the handle and feels very comfortable in the hand for both long and short cuts. The octagonal handle of mixed resin and metal components make it feel more solid and reliable than others. This knife is a piece of art in both form and function.
