Japanese blade Kurouchi Ajikiri Tosa 90mm

The knives of the Tosa masters have long been famous for their very high quality and reliability and need no introduction. The region where these knives are produced is located on one of the southern islands of Japan (Shikoku Island) and is widely known for festivals of knifemakers and manufacturers of a wide variety of cutting tools. The interest of professionals in various industries using knives, collectors, as well as just lovers of this subject is caused by both the high skill of manufacturers and excellent product quality, and the fact that due to the high competition of blacksmiths in this region, it is possible to purchase exclusive samples of knives made from the best grades of steel ( such as, for example, Aogami) for a relatively low price. Moreover, Tosa sells both ready-to-use products and blades separately (knife manufacturers in Japan, as a rule, are extremely reluctant to do this), and the handle can be made at your discretion, it can be very convenient. The presented knives are made by the Tadayoshi forging company under the guidance of master craftsman Tadayoshi Saku.
Ajikiri Tosa Kurouchi is a blade for making a small but very handy knife for cutting small products in the kitchen. Since the knife is Japanese, then, of course, the main purpose of it among the Japanese themselves is cutting fish - medium and small (the size that can be placed in a pan). Already in the name Ajikiri, the scope of this type of knife is indicated. The word Aji is a word that conveys a generalized designation for more than 50 species of fish, such as hake, mackerel, mackerel, horse mackerel, etc. Those. The sharp, thin, compact blade of the Ajikiri is best suited for removing the head, tail, fins, side shields, and complete butchering of such fish. But of course, in addition to butchering small fish, Ajikiri can be used in the preparation of meat and vegetables.
The length of the working part of the blade of Ajikiri Tosa Kurouchi is 90 mm, the height is 35 mm, the butt has a uniform wedge-shaped narrowing from the heel to the tip from 2 to 1 mm. The blade is a three-layer laminate with a central layer of Aogami steel hardened to a hardness of 61-62 HRC. The total length of the blade with the shank is 180mm. The Ajikiri Tosa Kurouchi Blade Knife is a very handy and practical knife for most jobs in the kitchen.
Ajikiri is divided into two types of Ajikiri with double-edged sharpening and Ajikiri with one-sided sharpening, which is essentially a smaller version of the Deba knife. Ajikiri with double-edged sharpening is less common, but is a more acceptable option for European cuisine.
The blade length of Ajikiri kitchen knife can be from 80 mm to 150 mm, along the length of the cutting edge, the most common size is from 80 to 90 mm. Like most Japanese kitchen utensils, the Ajikiri has a specific blade configuration; the Ajikiri's cutting edge is almost straight, with a slight rise to the point. This allows you to cut products with great comfort, and also greatly simplifies the sharpening process. Ajikiri's wide shank prevents hand contact with the table surface when slicing.
When operating and caring for a knife made from an Ajikiri Tosa Kurouchi blade, it must be taken into account that both the facing part and the solid core are susceptible to corrosion. Although most of the holomeni is protected by blackening (Kurouchi), it still does not completely protect against rust. Therefore, after each use, the Ajikiri Tosa Kurouchi knife must be washed and wiped dry. It is better to store it on an open magnetic suspension. If you do not intend to use the knife for a long time, it is advisable to lubricate the rusting parts of the blade with oil. The Japanese use butt oil for this. You also need to take into account that the central layer of the blade is very thin and hard, and the sharpening angle is critically small. It is necessary to avoid shock loads on the cutting edge, contact of the knife with something very hard (bones, frozen foods, etc.). Also, due to the fact that the central layer is very thin, with prolonged exposure to an aggressive environment, rust can completely destroy it.
