Chris, thank you so much. It took me weeks without result, yet you response in 30 minutes.
They must be katakana, right? I checked wikipedia's hiragana and katakana tables before i post (or even the whole "list of joyo kanji"), but didn't recognized any.
I claimed that this is my first "real" nihonto, but now that I know that it's a showato, and I don't see any forging pattern, is it a traditionally made sword?
I think I've been down this road before, where the question never seem to stop arising. Should have been satisfied with that Hanwei's practical katana.
"Encumbered forever by desire and ambition
There's a hunger still unsatisfied
Our weary eyes still stray to the horizon
Though down this road we've been so many times"
Again, thank you Chris.
West.
