"Damascus knife SUMINAGASHI Gyuto, 11 layers"
The knife series Suminagashi
Each of these traditional Japanese chef's knives is individually forged by master Toshiki Nanbu. Nanbu san, born in 1940, is a third-generation master blacksmith. He learned his art from Yahichi Nanbu, first generation, and Masamichi Nanbu, second generation. Forging is done in the traditional forging technique of Echizen Takefu, which aims to forge the knife blades as thin as possible, thus obtaining lightweight knives with very good characteristics. The Suminagashi series features a unique pattern, called the ink flow pattern, created by the 11 layers and the Black Smith finish on the upper part of the blade. The carbon steel used to forge the series has about 1.1% carbon and about 0.3% chrome. All knives are ground at an angle of approximately 15° on both sides.
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, slight deviations from the exemplary picture are therefore 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 dishwashing 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.
