During the middle battle ages in Mono province, the remarkable sword maker group KANESADA 兼貞 appeared in Hachiya (now Kami hachitya, Hachiya-cho, Minokamo-city), guessed 5 generations were active throughout Muromachi period.
The 3rd gen. KANESADA 兼貞 with Uemon-no-jo 右衛門尉 title who enjoyed Izumi-no-kami 和泉守 reportedly belonged to the 1st gen. KANESADA 兼定.
He has been evaluated as a superior sword maker next to KANESADA 兼定, KENEMOTO 兼元 and KANEAKI 兼明.
The subject work is full of Samurai majesty spirit during the Warning States of period when major powerful clans such as Oda or Toyotomi in Owari, Tokugawa in Mikawa, Imagawa in Suruga, Takeda in Kai and Hōjo in Odawara began rise to power.
Hirazukuri-construction was designed working well for cutting through the openings of armor or helmet, Itame forging ware of functional mixture with hard and soft steel was designed for durable construction, Suguha tempering was carefully quenched for the most supreme sharp performance and "Muneyaki" was designed for defending against hard hitting.
This prominent powerful wakizashi had been treasured by brave Samurais in generation and still remains very good condition for the passage of 500 years or even more.
