Am I totally off base with this blade?
I was looking at Shibata Katsuie's naginata
and Hiraoka Yorisuke's katana https://nihonto.com/4-1-23-2/
and noticed similarities with my sword .
It is signed "Waka" on the suriage nakago and has remnants of katte sagari yasurimei.
The hamon seems to be midare and widens as it approaches the monouchi.
Kissaki is chu and boshi is yaki ga fukai (almost ichimai) with slight kaen and hakkikake with a strong kaeri.
It has a tight nioiguchi in nie deki. hada is itame. Has yo, tobiyaki, sunagashi, yahazu, hotsure, and tall reaching loops.
Would this be way off base?
