Katsumasa

NOSHUu SEKI JUu KOJIMA KATSUMASA SAKU.
See KAT75.
I see a "Showa stamp" above the first kanji.
This is a WWII blade.

Pete

fire?

Looks like all 3 of your blades were in a fire?
Unless there is something strange about your photography...
If they are "yaki" (burned), I hope you didn't pay much for them, because they would have very little value...
