Atoma

Atoma is a Japanese line brand made by Tsuboman for the electroplated diamond abrasive. Founded in 1867, originally making files that are used for several industries. In 1981, they decided to shift their manufacturing from traditional files to diamond-embedded abrasive tools, which also meant changing their regular files into diamond files using electroplated diamond technologies. Now, Atoma is the favorite tool among knife or tool sharpeners for its versatility and robustness.
