This piece is an unsigned katana with a slightly greater curvature. The sword is well preserved, with no defects from forging, dents, or chips, but there are some light scratches in places.

The blade of the cutting edge has marks as if it has been slightly hit. Overall the sword is a little cloudy, but the hada and hamon are clearly visible. The hada has itame mixed with mokume everywhere and active hataraki such as chikei and yubashiri. The hamon in suguha is thin, niedeki, and very calm. Boshi are yakizume.

If you wish to have uchigatana koshirae, we can make it for an additional fee (200,000 yen and up). Although unsigned, this is a good quality sword that is packed with enough katana to be worth seeing and is especially recommended for those who want to buy a real Japanese sword for the first time.
