Kanayama

Kanayama Tsukutomi was an active blacksmith who not only designed and sold his own blades through the traditional wholesale market, but according to his son, he also helped to fill other orders for different blade makers including Chiyozuru Korehide. Tsukutomi's son Tetsuo-san explained on 2 separate occasions to me that his father worked and was known as a "shadow blacksmith" in his capacity of making some of the blades for Chiyozuru. I have no evidence.

 

His son Kanayama Tetsuo, shown was born in 1950 and he has continued the craft and traditions of his father and at this time has gained a reputation for his fine small kiridashi kogatana knives and large survival type knives.One of Kanayama Tetsuo blacksmithing trademarks that he is known for is hisinventive and artistic use of kamaji and watestsu.

He is showing how to use a large wheel that was used for grinding out the ura on a kanna blade. The two wheels are nearly 5 feet in diameter and are impregnated with abrasive. These type of wheels were used for large production orders. I saw a wheel in the Ishido shop that was used for the same purposes.

Kanayama Tsukutomi was a blacksmith from Tokyo and the
blade pictured below was made by him in the 1940's or 1950's. It is known that his original workshop was in Tokyo and he excelled in his field until his death in 1960.

Following are some of the beautiful blades from the Kanayama shop, some are made by the current Kanayama Tetsuro, and some were made by his father Tsukutomi-san.

Kabutowari, circa 1950 is marked down the center KABUTOWARI (reference to weapon*), and to the left MINAMOTO (nom de plume) and TSUKUTOMI-ZO (made by Tsukutomi) and to the upper right is the makers logo.
