In the search for something cool and different, I came across this website:

which contains a lot of text about an alleged sword of ninjas, which was straight and of poor quality and design (!)

Is there any truth in these ninja-sword claims then? I thought the whole ninja thing was an 80s obsession that has been discredited and the claims about these swords have been proven untrue?

I'm confused. Whether it's true or not it still sounds cool though. Marketing gimmick??
