Soooo From the place the developed Thousands of years ago, the technique of Japanese sword making, polishing and sharpening Not just battle ready but Works of art Sent it you you What did Japan run out master craftsmen Riigghhhtt
Plus Your choice of music Sucks Considering the respect you seemed to show before even opening the box
That sword needs a good polish and clean, unless you like it like that. I am very surprised that Japan allowed a sword of that age to leave the country without trying to purchase it for its own museum. I hope you know what your doing put trying to restore this sword yourself.
I call bull shit ! That would mean it’s from Japan and because the laws of Japan say you can not take a national treasure out of Japan , well that means either your a lier or just so stupid you assume your sword is 400 years old or you just are in the habit of telling people lies , anyway it’s not 400 years old or from Japan and I can tell that from just seeing the blade on this video
