Tsunehisa Petty Kuro-uchi 80mm [Rosewood] is basically a smaller version of a gyuto knife (Chef's knife). Petty knives are intended for all those smaller tasks where larger knives are deemed unwieldy, both on and off the cutting board. A must-have knife in every kitchen, it can be used for peeling, mincing, paring and decorating food.

BLADE SHAPE:
This petty, sometimes also called a paring knife, is a small and highly versatile kitchen knife. Paring knives offer more dexterity, precision, and maneuverability than the larger, multi-purpose knives, therefore its main tasks are peeling, slicing, and trimming.

STEEL:
The core of this knife is Hitachi's Super Blue Steel (Aogami Super), which is the very top quality of traditional Japanese steels. The Kuro-uchi (black) patina on the upper part of the knife gives it a unique and rustic appearance. This knife was heat-treated to around 63 HRC. It is a very hard steel, meaning that it will retain a super-fine sharpness for a long time. In addition, due to the high carbon content (1.4-1.5%), the knife is very easy to sharpen. Among the high carbon steels, Aogami Super is also the least sensitive to rust. It also contains 0.4% vanadium as an admixture for micronized metal grains, which gives the steel more toughness. Aogami Super is rated as the most advanced carbon steel. The outer layers are of softer, stainless steel, giving the knife extra rust protection.

LAMINATION:
The core layer consisting of Aogami Super steel was sandwiched between two layers of softer steel. This technique is called san-mai and is used to protect the hard (but delicate) core from outside factors and physical impacts, which could lead to breakage.

The outer layers are of softer, stainless steel, giving the knife extra rust protection.

GEOMETRY:
It has a double bevel (symmetrical) blade.

BLADE FINISH:
Kuro-uchi finish, the unprocessed (black) part on the top side of the blade has already developed a dark patina, which protects the blade and gives it a unique and rustic appearance. The blade was treated with hammer blows, resulting in a textured tsuchime look, which gives it a beautiful finish and also prevents food from sticking to the blade.

HANDLE:
The handle (traditional Japanese Wa) is oval and smooth, with no discernible transition between the rosewood and maple wood. It’s suitable for both left- and right-handed users.

BLACKSMITH:
Tsunehisa knives are a brand that combines a variety of high-quality knives from various knife centers of Japan such as Tosa, Seki, and Sakai. Their philosophy is that each region has its own steel and different manufacturing processes. For example, Tosa is best known for its Ginsanko and Aus-8 steels, Seki is famous for making excellent blades from the V-Gold group of steels, and Sakai for its single beveled Honyaki knives.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.

☝️ THIS KNIFE MAY DEVELOP PATINA

Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:

✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
✔ After use, rinse it with lukewarm water and wipe it dry.
✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.

A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

→ For in-depth information about patina, read our dedicated post on patina.

GENERAL KNIFE CARE TIPS:

Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:

✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.

❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
