Sorry I know this question sounds stupid - am a noob in case it wasn't already clear. But I've been told that the best way to develop an eye for the real deal is to look at examples with your own two eyes. Ok, fair nuff, but they don't exist where I live and I find neither pictures of swords nor articles written by experts tell me a whole lot...tbh I'm kinda disappointed that I've spent so long reading up as much as I can about nihonto but I still can't tell the difference between a fake and a real antique. Sometimes I ask an expert why they say a particular blade looks fake and even their answers just fly right over my head. They cite things like a tsuka ito that looks like shoelace (which usually just looks the same as a really old silk ito to me) or a fake patina (well how do you even tell if it's fake??), but no matter how one explains it I guess I just don't have the feel for it. Also I felt really stupid when I saw this video below and thought it showed real nihonto, maybe national treasures or something...but no. They were just chinese fakes, and I was ooh-ing and ahh-ing at them. Ughhhhhhhhh.
Anyway I guess I just wanted to know wtf I'm doing wrong and maybe get some reassurance that I'm not a complete idiot. Thanks. (What an introduction, I know...)
