TSUBOE - Metal blade production since 1907

When the founder, Kotaro Kasahara started manufacturing files, it is said that there were as many as 400 file factories in Tsubame City. Today, there are only three companies manufacturing files in Tsubame City.

It is said that the word “tsubo,” which inspired our company name TSUBOE, is derived from a jar containing lead, which is used to anneal the steel used to make the files. Kure City in Hiroshima Prefecture, known as a production center of files, also has many company names and products named “TSUBO”, which is said to be attained from the jar containing miso applied to steel during quenching to improve hardness.
