over 90 years In Seki, the Japanese center of the blade production




Seki is a very famous city for the production of the cutting blades with an 800-year history originally from the swordsmiths for katana, a long, single-edged sword used by Japanese samurai.

Such craftsmanship and spirits related to the sword making, which create strong and sharp edges with a unique smithing method called Seki-den, have been handed down over many years from generation to generation, making Seki known as one of the world’s top three centers of blade production, along with Solingen in Germany and Sheffield in the United Kingdom.

Tenken has been established at Tawara district in Seki since 1932.

We have devoted ourselves to the in-house production of the precise cutting tools and blades, improving our technical expertise over 90 years.

And we have successfully gained trust due to our long history of achievements with our craftsmanship honed through our ancestral DNA for 3 generations, which has allowed us to invent any products from scratch including toolings such as jigs, molds and machines.
