"AS Petty Kiritsuke Tsuchime 150, Ebony Handle"
Nigara Hamono - Since the days of the samurai
The sword and knife forge Nigara Hamono can look back on a tradition of over 350 years. During the early Edo period, the city of Hirosaki was a castle town. There were over a hundred forges in the area at that time. Nigara Forging is one such historic forge located in Tsugaru, north of Hirosaki, which has preserved and maintained its craftsmanship to this day. The forging techniques used by Nigara are essentially the same as the traditional forging techniques that have been used for centuries to make high-quality sword and knife blades. The folding and hammering of soft iron and steel creates a distinctive beauty in each knife Nigara makes.
Knife Series AS Tsuchime by Nigara
This series of knives is already special because of its origin, the forge Nigara. Visually, it is characterized by the bright finishing of the upper part of the blade and the distinctive hand-beaten hammering. However, you will only experience the full character of the knives when you use them in your kitchen. The knives have a very good, balanced weight distribution, are thinly forged and very sharp. The hard steel of the cutting core, forged to about 62 HRC, offers excellent sharpening potential. The cutting core is made of Aogami Super, the blue paper steel. The steel is a genuine Japanese carbon steel and can be forged very hard. It features the finest martensite - metastable microstructure - which provides higher hardness and excellent sharpness. Another advantage is that Aogami super can be easily sharpened despite high hardness and shows very good stability due to the high percentage of tungsten. So with this cutting core, the knives in this series offer exceptional sharpness, cutting performance and durability.
How to use
Japanese chef's knives are made of extremely hard steels and are forged and ground thinner than their European counterparts. Some of these knives have very finely ground cutting layers, making them more delicate and suitable only for soft cut foods. Please refer to the product details for information in this regard. In particular, knives with a very thin cutting edge and hollow grind are prone to chipping on the blade. These are excellent for fine cuts of soft cut material, but should be used with appropriate care. Sharpening on a whetstone usually produces an angled grind, which makes the edge more stable over time.
Breakouts on the cutting edge can also occur due to leverage forces as well as frozen cuttings, which significantly reduce the temperature of the steel. Leverage forces often occur when cutting material with bones, for example. Chipping on the cutting edge may need to be ground out by a professional.
The knife should always be guided straight with pulling or pushing cut, without much pressure. To maintain sharpness, avoid cutting on stone, glass or other hard surfaces. Never use \"sharpening steel\" for resharpening. Water sharpening stones are recommended (grit: 400-1200 for preliminary sharpening, 3000 for fine sharpening, 6000 or more to strip the blade) and a honing leather if necessary.
Please keep the knife away from children. These knives are extremely sharp, please be careful.
All products are unique, so slight deviations from the exemplary picture are possible.
Care instructions
When using knives made of delicate types of steel, such as Aogami, Shirogami or V-Toku, please clean them occasionally with a cloth and water even during prolonged use. However, acidic foods can still cause discoloration on these classic carbon steels. After use, please wash by hand with hot water and use a neutral detergent if necessary. Please do not put the knife in the dishwasher under any circumstances. After cleaning, dry thoroughly, oil if necessary, and store in a well-ventilated area. Residual moisture can cause rust in non-stainless steels. See our posts on the ORYOKI Japan blog for product care.
Clean the knife by hand and do not use a dishwasher. Dry it thoroughly afterwards.
