Great resource, Peter, and thank you for posting it... it provides a good primer for differentiating between the major styling cues of real versus fake nihonto and koshirae, with enough detail to keep (most) novice collectors aout of trouble. IMO an overwhelming number of knock-offs (90+%) can be identified using this guide.
Regarding the Type 95 NCO swords, there is still, IMO, an unmistakable difference between the fakes/repros and the originals the fakers have yet to bridge. This might sound odd, but I find the originals tend to have a smell about them lacking in the fakes.
I am, however, in David's camp that hands-on experience is of equal (and of considerable complimentary) value to reference volumes... gunto aside, there are plenty of affordable nihonto out there that give the aspiring collector a reference point by which they can study features of legitimate examples (e.g., hada, hamon, yasurime, etc.) in the hand.
