This product is for those who place even more importance on sharpness than the Extreme Series.

*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.
