Medium carbon steel Japanese-style closing knife

Description

Material characteristics

The carbon content of medium carbon steel is generally between 0.25% and 0.60%, which can give consideration to both hardness and toughness when it is used to make cutting knives. Compared with high carbon steel, medium carbon steel has slightly lower hardness but better toughness and is not easy to break. Compared with low carbon steel, it can keep a good sharpness of the blade, and after proper heat treatment, the strength and elasticity of the blade can meet the requirements of iaido practice.

manufacture craft

Forging: medium carbon steel is heated to high temperature, and impurities are removed by repeated beating and folding, so that the internal structure of steel is more compact, the texture is more uniform and the performance is improved.

Quenching and tempering: after heating to a specific temperature, it is quickly cooled and quenched to make the blade hard, and then tempered to eliminate stress, prevent cracking and deformation, and increase toughness.

Grinding: Fine grinding with different mesh grindstones, from rough grinding to fine grinding, makes the blade smooth and sharp, and also shows the steel texture.

appearance design

Blade body: The blade length is generally about 60-70cm, with elegant arc shape and sharp tip, which gradually narrows radially from the blade cluster to the tip, and gradually becomes thinner axially. The cross section is mostly made of picks or cutting edges, and the surface of the blade body has textures left by forging and grinding.
Handle: It’s longer than the ordinary knife handle, which is convenient for both hands to hold and draw the knife quickly. It is usually made of solid wood, such as cypress and sandalwood, wrapped with silk thread or leather, and inlaid with metal decoration.

Sheath: mostly made of wood, the surface is painted or wrapped with mackerel skin, and the scabbard mouth and scabbard tail are reinforced with metal fittings.

Functional use

Iaido exercise: Its design conforms to the requirements of iaido’s techniques, helping practitioners to master the actions of drawing, chopping and closing the knife, and improving their skills and reaction speed.

Collection decoration: exquisite craftsmanship and unique appearance make it collectible, which can be displayed at home or office to show taste.

Maintenance method

After use, wipe the blade with a clean soft cloth to remove stains and moisture, and apply a small amount of antirust oil; Store in a dry and ventilated place to avoid direct sunlight; Check the blade, handle and scabbard regularly, and repair them in time if they are damaged.
