A Suishinshi Masahide Wakizashi (水心子正秀)

Suishinshi Masahide is the founding father of the Shinshintô period – the smith who, more than any other, redirected the entire course of Japanese swordmaking by championing the return to classical Kotô methods. To hold a blade by Masahide is to hold a piece of that movement in your hands. This wakizashi, dated to the second month of Bunka 7 (1810), represents him working at the height of his powers in the Sôshû tradition, producing a deliberate and respectful tribute – an utsushi-mono – to the legendary Goro Nyudo Masamune.

The hamon is spectacular: a full hitatsura in pulsing nie-deki, combining gunome midare, notare midare, and islands of tobiyaki that seem to swim freely in the ji. Sunagashi sweeps through the hardened zone like breath through sand. The visible nie crystals are dense and brilliant throughout. The jihada is ô-itame – large, open wood-grain swirls characteristic of the Sôshû tradition – capable of withstanding the extreme temperatures of the yaki-ire quenching process that produces this kind of volcanic activity in the steel.

Wide and long for a wakizashi, with a shallow curvature, this blade carries the presence and authority of a full katana. The nakago bears Masahide’s signed name alongside his koku’in stamp – the personal seal derived from the characters for “sun” and “heaven” (日天) that he used from 1806 onwards. The torokushô (registration card) bears the serial number 1522 and is dated to Shôwa 26 (1951), the very first year swords were formally registered in Japan, a detail that speaks strongly to the blade’s provenance within a prominent collection.
