As you know during wartime, Accountable swords were made during wartime.
Yasukuni shrine blade is a well-known swordsmith because of the high quality.
These swords were made careful attention for polishing and quality itself.
But for instance Nagamitsu and Emura also made a lot of blade with poor polishing.
But if you check the blade more carefully,some Nagamitsu
and Emura is remarkable work much better than Yasukuni blades.
I think in the near future, Other Gendai blade including Emura
and Nagamitsu will be re-evaluated.
From Aoi-Art: Emura who was a prison director invited Nagamitsu,
who was a swordmaker of the army and taught sword production to prisoners.
Emura chose good works and polished them. Nagamitsu made many swords,
polished easily and sell to army officers. Consequently,
There is a clear difference between Emura and Nagamitsu due to good
and bad polishing.
