Nigara Kiritsuke SG2 Damascus 240mm (9.4″)

Nigara Kiritsuke SG2 Damascus 240mm is a multi-purpose Japanese kitchen knife, suitable for preparing meat, fish and vegetables. Its SG2 powder steel core insures long-lasting sharpness with little to no maintenance, as the steel resists corrosion very well.

It’s hard not to notice the eye-catching and masterfully made damascus finish on the blade, which is dotted with circular elements, also known as a raindrop damascus pattern. This kind of damascus finish, also called the “Anmon” technique, is now almost a trademark for Nigara Hamono and draws its inspiration from the majestic Anmon Waterfalls and the breathtaking sight of rippling water beneath them. 

Another feature that catches the eye is the reverse-tanto tip, also known as a “K-tip” (K for kiritsuke) that slopes downward from the spine and has some great practicality, as it enables precise and effortless work with the tip. The belly of the blade is curved, which differentiates it from a standard, flatter kiritsuke shape and makes it a sort of kiritsuke-gyuto hybrid. This means that the knife can be utilized really well for rocking motions too.

BLADE SHAPE:
Kiritsuke is a multi-purpose blade shape, characterized by a long, flat blade and a special tip, also called a reverse tanto or kiritsuke tip (“K-tip” for short). The long blade will work great for preparing larger pieces of meat, slicing fish and chopping vegetables, while the tip can be utilized for intricate, precise work. Traditionally, kiritsuke knives were single-beveled, but have since often been reimagined as double-beveled multi-purpose knives to meet the demands of fast-paced tempos of modern kitchens. They were also only allowed to be used by the Executive Chef of the restaurant, but we’ll look away if you’re not (yet) the head chef 😜.

*The length of the cutting edge is 225mm (heel to point), but with this knife the length is measured from the edge of the handle to the tip of the blade, amounting to 240mm.

STEEL:
SG2 steel is a powder steel, renowned for its hardness and subsequent edge retention—due to a high carbon (C) content of 1.5%. The steel is also high in chromium (Cr)—around 15%, which adds to corrosion resistance and Molybdenum (Mo) that improves the blade’s wear resistance. SG2 steel blades will be able to achieve a fine sharpness due to the fine microstructure of the steel and will keep it—without having to worry about maintenance and corrosion.

LAMINATION:
A high hardness of around 64 HRC means that the blade won’t be very tough, so the blade’s core was laminated using the san-mai method to improve its structural integrity and subsequent ability to withstand impacts and prevent chipping. San-mai translates to “three layers” in Japanese, referring to a blade that is composed of a primary, inner layer of harder steel (hagane) and of two secondary, outer layers of softer steel (jigane) that protect the prior.

GEOMETRY:
It has a double bevel (symmetrical) blade with convex (full hamaguri) grind. Hamaguri grind allows superior sharpness that requires delicate handling and helps to prevent food from sticking to the blade. Such a shape keeps a lot of metal behind the edge and makes for a stronger edge, yet it still allows a good degree of sharpness. The downside to a convex grind is that it is very hard to reproduce by anyone other than a very experienced sharpener.

BLADE FINISH:
The blade is adorned with a raindrop damascus pattern. The cutting edge has a forced patina to match the dark gray appearance of the blade.

HANDLE:
Japanese (Wa) style wenge wood handle with a buffalo horn ferrule. 

BLACKSMITH:
Nigara Hamono has a 350-year history, making swords since the Edo period. Head blacksmith Tsuyoshi Yoshizawa, who works alongside his father Toshi Yoshizawa, is an eighth generation blacksmith with a passion for art and music as well as knives, and his famous Nigara Anmon design is the result of his love of Andy Warhol’s artwork. Nigara is easily one of the most special knife makers in Japan.
