KITAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!
"Phew... Japanese swords are amazing"!!!!!!! Superior Nippon steel being best in the world simply cause it's Japanese, FUCK YEAH!!
I wonder if we'll also get superior Japanese food. Natto is obviously the best in the world simply for being Japanese too.
Also, don't know the names in English (studied in Spanish), but while Diamond is "hard" (i.e., you can't cut it or pierce it unless you also use diamond), it's not "insert-word-here" (meaning, a simple hammer would smash it into a million tiny pieces). I doubt you could take down a wall with that...
But well, "a God made it", so whatever.
