Tsubosan BREX Flat Coarse/Fine

This is a non-clogging Tsubosan original product, and its selling points are the feeling of sharpening that is not found in conventional files, and its excellent ability to remove cutting powder.
Special hard chrome plating provides excellent chip removal properties, with almost no clogging of the file, and chips can be easily removed, ensuring sustained sharpness.
Durability is 3 to 6 times greater than previous products from the same manufacturer (varies depending on the material being cut).
It has excellent rust and corrosion resistance, and prevents deterioration due to rust in humid environments and marine environments.
It has a surface hardness of HV900 (HRC67) and the grain of the front and back is different, so one tool can be used for everything from rough cutting to finishing.
Non-slip foam resin grip.
Cutting soft materials such as wood, wax, plastic, aluminum, copper, steel, stainless steel, ceramics, and other hard materials.
*Do not use for purposes other than its intended purpose. For safety, wear protective gloves and glasses while working. Make sure there is no wobble in the handle. Do not force the file or use it as a hammer. It may break, which is dangerous. If it becomes clogged and difficult to file, remove the chips with a brush before using it again. When storing, remove the chips with a brush, wipe off any moisture with a dry cloth, and then apply a thin layer of low viscosity oil before storing.
*The abrasive powder remaining on the surface may rust and turn brown, but this does not affect use. Never use this product on tools that require a high level of sharpness, such as hairdressing scissors, high-end scissors, pet scissors, or fabric scissors. Do not use this product on new tools or tools that have not yet been dulled. Do not use this product on tools that would be damaged if scratched.
