Explanation
Kinjū was traditionally regarded as being one of the Ten Students of Masamune. It is said that
he came originally from Tsuruga (敦賀) in Echizen province and moved then to Mino where he
founded together with Kaneuji (兼⽒) the Mino tradition of sword making. There are only very
few signed works of Kinjū extant. Compared to the workmanship of the Shizu School, his blades
very often show a more standing-out hada and a hamon that rather features a connected gunome
with roundish yakigashira than a gunome that tends to pointed togari. His ha is hardened in ko-nie deki and in general it can be said that his works are overall a hint more calm as works of the Shizu
School.

This blade was originally of a long nagasa and with its wide mihaba and little protruding tip
section, it represents the typical classical naginata shape of the Nanbokuchō period. The jigane is
a densely forged itame that is overall mixed with much nagare and masame and that features plenty
of ji-nie, fine chikei, and prominent utsuri-like shirake. The hamon is a nie-laden suguha-chō with a
bright nioiguchi that is mixed with connected ko-gunome, some hotsure, and fine kinsuji and
sunagashi whose elements appear overall in a relatively angular manner. Thus, the jiba reflects
very well the characteristic features of Kinjū. The steel is with its kitae in itame and masame quite
bright and of excellent forging quality and the hamon displays much strongly sparkling nie and
therefore the blade is of a superb deki
