After that ge moved to Edo and worked for Kuwana domein wordsmith.
He was well known sword maker in Edo period so he made a lot of swords during that days.
His reputation was very high because his skill is quite high and nothing rubbish sword left.
I have never seen worst one.
His subjects are overwhelmingly Gunome midair hamon and midarekomi boshi.
The sword are very similar with Cyounsai Tsunatoshi.
The differences of these swords are Tsunatoshi' s gunome midare devided 2 and round boshi but Munetsugu is not devised and boshi is midarekomi style.
If the round shaped boshi, you should doubt the signature.
