Carbon steel roasted blue handmade integrated Japanese style command knife

Description

Materials and workmanship
Carbon steel material: carbon steel is used as the tool body material, carbon steel has good toughness and hardness, which can ensure the strength and durability of the tool in the process of use, and after suitable heat treatment, the tool body can have good cutting performance and anti-wear performance.
Blue baking process: The blade is blued, which is an anti-corrosion process for the surface treatment of steel parts. By placing the iron in the furnace and baking it red, take it out and put it in diesel fuel for cooling, or oxidize it in the solution of concentrated alkali and oxidant, etc., so that a dense blue protective layer of ferric oxide is naturally generated on the surface of the utensil, which can not only isolate the product from air and moisture, enhance the corrosion resistance, but also increase the aesthetics.
Hand-forged: The blade is made by hand-forging. The blacksmith heats the carbon steel material to a high temperature to make it in a malleable state, and then uses a hammer and other tools to hammer it repeatedly, in this process, the internal structure of the metal is optimized, and the impurities are discharged, so that the density of the blade is higher, the texture is more uniform, and the toughness and strength are further improved, while the hand forging can also give the knife a unique personality and artistic value.
Design
Knife Blade: Generally slender, usually about 70 cm long, the overall line is smooth and straight, gradually narrowing from the root to the tip, and the tip is sharp, which is conducive to stabbing. The sides of the blade may be split to reduce weight, increase strength, and direct blood flow when cutting, while also increasing the aesthetics of the knife.
