Note: This is a list of corrections, not a rebuttal. Your vote won't be lowered by half unless someone continues this into a rebuttal or you strike up a debate.

Though it was damn close to being one due to all the inaccuracies.

That's pop-culture, not metallurgical fact. Evidence shows that katanas were no sharper than any other sword.

None of us said that. I think I've quashed that myth pretty hard; as mentioned, folding was to mitigate the poor quality iron used, and the technique is hardly unique to Japan.

This is true of any sword. As long as it's well-maintained and cared for, a sword can retain its edge for quite a while. Especially if it's a family heirloom/display piece that doesn't see combat.

This is pure, utter bullshit. The flat grind, or "triangle grind" as you call it, is not unique to the katana. Further, most cutlasses were saber ground, not hollow ground, which resulted in a similar edge. Finally, a hollow grind actually results in a sharper, but less stable, edge.

This is also false. The katana and cutlass are, as I mentioned above, of a similar sharpness. No edge can "cut on its sharpness alone." Both the katana and the cutlass need momentum behind them to cut.

There's no evidence to suggest this.

This is directly contradicted by his weapon descriptions. He has trained with them and used them proficiently, with the possible exception of the Katars. Though the "still learning" is incredibly vague.

Even Myamoto Musashi, Japan's greatest swordsman, acknowledged that dual-wielding required years of specialized training in dual-wielding techniques. Since Norio preferred to use a single blade, it can be inferred that he doesn't have this training.

I did mention that pictures aren't meant to be of the equipment in question, just generic photos. Not realy a correction, just something I'd like to point out.
