From Our Representative

Our company was founded in 1940 (Showa 15) as a manufacturer of metal cutters.

Since that time, we have been steadily walking along with the postwar reconstruction, high economic growth, and the rapidly changing Japanese economy.

When it was said that "iron is a nation," we have also made cutlers with a focus on metal cutting, and have manufactured and sold cutlery to contribute to society.

However, nowadays, as society has matured, it has become essential to consider not only the economy but also the environment.

The role required for metal cutters also varies from cutting to crushing to crushing.

We believe that it is our mission to reach the foundation 80 years, to send to the society "blades" that can meet these demands.

In order to fulfill this mission, we will work together as a team.

We look forward to your continued guidance and encouragement.

We at NANIWA SAW & KNIFE MFG will remain diligent in the continued pursuit of product development and technological improvement.
