This is a high-grade iai of Masamune made by Niagi.
This is a later production model, characterized by its kakitsume groove and polished , designed also for display.

As it is constructed for iai-do, it can be used without issue for kata practice or suburi (swinging practice). It produces a light whoosh sound when swung due to the groove.
*Please note that it is not durable enough for sparring practice. Also, if you use it for practice, please ensure regular maintenance.

The has some minor scuff marks and age-related wear, but it is in relatively clean condition. There is no looseness in the koiguchi (mouth of the scabbard).
Please confirm the condition from the photos and purchase only if you are satisfied.

Nihon Antique Gallery has ceased manufacturing iai , making this a rare piece.
The Masamune , which was Niagi's flagship model, is particularly beautiful in its hamon (temper line) and koshirae (mountings), offering a sense of satisfaction just by owning it.

Please consider this opportunity.
*As this is a low-price listing, please refrain from significant price reductions.
