Blade condition: In fine polish, with no flaws. Minor surface scratches and very minor oxidation.


Buke-zukuri. Black laquered saya, tsuka bound in black ito. The same is in very good condition, and would apear to be a full wrap. The habaki is, at 1.53 inches (38.90 mm), quite long. It has a falling rain design. The tsuba is made of iron, whilst the fuchi-kashira is of iron, copper and gold. The kashira has gilt shitodome.

See pictures below.


Most definitely not a military sword. This was intended, from the first, to be a civilian sword. If it is, as seems likely, a Gendai blade, then it belongs to the period before WW2.
