Nigara Kiri-Petty SG2 Migaki Tsuchime Wa Ebony 95mm (3.7″)

Nigara Kiri-Petty SG2 Migaki Tsuchime Wa Ebony 95mm is a small Japanese kitchen knife, intended for smaller tasks where larger and wider knives are deemed unwieldy. It’s small form makes it excellent for cutting tasks such as peeling, paring, trimming, as well as other in-hand cutting, for example coring apples or removing the eyes from potatoes. The pronounced “K-tip” proves very useful with fine, decorative work with vegetables and fruit, as well as with trimming and skinning meat, as it’s great for piercing through the skin.

Its core is made of SG2 powder steel, ensuring long-lasting sharpness while requiring minimal maintenance. The steel’s excellent corrosion resistance makes it a reliable choice for kitchen use. The hamaguri grind gives the knife better piercing capabilities, while the unique hammer indentations ensure that ingredients do not stick to the blade during cutting, allowing for faster and more precise work.

BLADE SHAPE:
Petty knives are designed for smaller tasks on and off the cutting board. It’s an indispensable knife in any kitchen and can be used for peeling, mincing, paring and decorating food. The blade is finished with a “K-tip” tip, typical of Japanese swords and daggers. Petty or utility knives are basically a smaller version of gyutos or chef’s knives. Due to the length of the blade, it can also be used as a stand-alone knife if you are not comfortable with longer blades. A must-have knife in every kitchen!
Use for: peeling, trimming, garnishing, carving, chopping herbs, chopping garlic, slicing small pieces of dried meat, trimming meat, filleting small portions of fish, and similar tasks.

*The length of the cutting edge is 85mm (3.3″) (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 95mm (3.7″).

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 piercing and 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 surface of the blade was treated with a special textured hammer, leaving complex geometric impressions on its upper part. The Japanese hexagon hammered finish on knives is a stunning technique that involves skillfully hammering the blade’s surface to create captivating hexagonal indentations.

The tsuchime surface helps to reduce friction and prevents food from sticking to the blade during cutting. The textured surface creates small air pockets which allow for smoother and more precise cutting.

In Japan, the hexagon is prized for its aesthetic appeal and structural stability in traditional arts, crafts, and architecture. It is found in various artistic forms and is also used in the design of Shinto torii doors and modern buildings. The hexagonal shape of the kasagi in torii doors represents the belief in strength and stability associated with the number six.

HANDLE:
The blade was fitted with an octagonal traditional Japanese (wa) handle, made out of ebony wood with an octagonal shape, so it will fit equally well into the hands of right- or left-handed users. Ebony is used because of its incredible features (hardness, strength, and rich aesthetic, including its dark color, visible grain), and rich cultural heritage.

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.
