Answer.
1:The blade is very healthy wide and thick and longer kissaki.
At Late edo period, these healthy blades were made.
2:Jigane is very tight koitame hada.
At the end of Edo period, nice Jigane(iron) was imported from Europe
and also iron making factory was established and developed iron-making
technology. Sword makers made swords by using this steal.
Ironically,Japanese sword makers introduced western steal and abandon
Japanese traditional Japanese steal by using iron sand.
3:This kind of Gunome midair hamon made by Koyama Munetsugu and Cyounsai Tsunatoshi.
The hamon of the Tsunatoshi divide 2 pieces and round shape kissaki hamon.
meanwhile Koyama Munetsugu made regular Gunome midair hamon and midarekomi style boshi.
4:Koyama Munetsugu has Saidanmei (Kiritsuke mei:cut the Tameshigiri on the Nakago)
He made Few saidanmei by Kinzogan(gold inlay).
I think making Kinzoganmei is expensive and also require great care.
