Hand-crafted using R2/SG2 high-speed powder steel, this kiritsuke petty knife is beautifully grinded with superb thinness behind-the-edge supported by the 62-63 HRC hardness. Being a guru of steel manipulation and expert on steel construction, Nigara Hamono created a unique Tsuchime pattern that is reminiscent of industrial steel beam, while the Kurouchi finish gives this knife a characterful accent. The fit and finish is superb for a Kurouchi knife, with a smoothly polished choil and refined Kasumi on the grind. 

Note: the shade of darkness of the kurouchi finish (the darker part of the cladding) can vary. The kurouchi may appear to be slightly darker or lighter than what's shown in the photo.

About Nigara Hamono 二唐刃物

With 350 years of history, starting from making swords for Tsugaru clan in the early Edo period, Nigara Hamono has passed down knowhow and skills for eight generations. Its 5th generation blacksmith Kunitoshi Nigara was a legendary sword maker, earning a long list of accolades, honorary titles and knighthood. The current (8th) generation blacksmith — Tsuyoshi Yoshizawa is supported by his father Toshiju Yoshizawa who has keen interests in art and music. Nigara’s famous Anmon design is the result of Toshiju’s love for Andy Warhol’s artworks. The family business’ expansion into construction steelworks has given Nigara unmatched access to in-house knowhow when it comes to advanced finishing. All these set Nigara apart as one of the most special knife makers in Japan.

Care:

Wash and dry with a soft sponge, and safely store after use. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
