I had the chance to buy a real one from a couple of hundred years ago, but it the price was astronomical, it was about 30,000 American dollars for it, plus, i would have had to go to Japan to get it.
I have 3, two for navy/military ceremonies and one is a Spanish toledo double handed sword with a crucifix attached to it. It was used 600 years ago (not mine but the type of sword) for beheading heretics (apologies to heretics).
ATTENTION! I got angry!
These days made in Korea sword are sold.
They are Spring steel poor sword.
Koreans are insisting that the Japanese sword is Korea origin.
We call [ Japanese culture as KOREA origin] uriginal.
