The long blade is shinogi-zukuri with a iori-mune. The hada is a prominent flowing itame, and has a pale, prominent utsuri. The clear bright hamon is a suguha based ko-gunome with choji, ash and yo. There are some more prominent shoji in the upper part of the blade. The boshi is suguha, ko-maru with a small turn-back. The unsigned nakago ends in iriyama-gata and has katte-sagari file marks.
It comes in a modern katana koshirae, with a plain black lacquered scabbard, with a gold colored silk sage, and a black silk on white ray-skin wrapped hilt. The hilt fittings are iron, and the antique menuki are shakudo with gold colored grapes. The iron tsuba has a carved design of a dragonfly.
