As mentioned, this is a flawless perfect sword. The jigane is an extremely beautiful, rich ko-itame with chikei and ji-nie. It gives the impression that you are looking at one of the better Hizen smith’s work. The hamon is suguha based, with small ashi. What makes this sword really exceptional is the strong utsuri, which is trademark for shinto Ishido but generally rare in shinshinto.

The shape is a powerful one that evokes the feeling of Nambokucho. The moto-haba is a wide 3.3cm. The blade has an extended kissaki. The kasane is a thick 7.5mm. As mentioned, the blade is signed Chikushu Ju Koretoshi and the nakago is ubu. The sword measures 66.5cm.
