The tradition that has been sharpened,
brightened and innovated by the times

Files are used to sharpen things and make them brighter.

The history goes back to ancient Greece.

Nigata files came from Osaka in the Edo Period.

We founded our company here in Nigata to make tools for agricultual and
industrial needs having tradition and innovation in our mind.

And now our files are enhanced with diamond.

With the hardest mineral on earth,
innovation makes our tools brighter and our customers happier.
