Fu-Rin-Ka-Zan HAP-40 Series Kiritsuke (210mm to 270mm, 3 sizes, Octagonal Bocote Wood Handle with Water Buffalo Horn Ferrule)

 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.

We have worked closely with historical & professional Forge-Smith Sukenari for making the Fu-Rin-Ka-Zan HAP-40 Series Knives. Sukenari’s knowledge of traditional forging processes and their extensive experience with modern, high-performance steels proved to be invaluable when 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, relative to ZDP-189 and Aogami Super knives, these new HAP-40 knives offer very competitive cutting performance and edge retention. In addition, even when HAP-40 is heat-treated to a higher Rockwell hardness than ZDP-189, HAP-40 offers better toughness. Consequently, Master Hanaki has confidence that these HAP-40 knives will prove to be some of the best performing and most practical knives from Japan.

 Fu-Rin-Ka-Zan 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 Magnolia wood Saya (Sheath) with a black pakkawood Saya pin. (Both we and Sukenari requested the Japan’s selected experienced Wa Handle Craftsman for handcrafting the Octagonal Bocote Wood Handle.)

 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.

About Left Handed Version

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. 

Instructions & Maintenance

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.

Important

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.

• Please do not put the knife in the dishwasher machine for cleaning.
• Please do not leave the knife in water or wet condition for a long time.
• After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes, and keep it in a dry place.
• This is an extremely sharp knife. Please use special cares in using and storing it.
• Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.
• Please do not use it to cut bone or frozen foods, any hard shell foods such as lobster and crab.
• We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.
