I gotta say, I've owned my spyderco Endura for... almost 3 days now. First spyderco knife, this is my second (or third?) post on this forums. As a fairly uninformed observer, there's lots to pay attention to here. OP making shady claim without really following up. (time from post, to youtube video, and no follow up info, no pictures, no back-and-forth) The community here on bladeforums response to OP about sharpeners, technique, and possibilities for the problems described. (not talking about Sal at the moment) And then Sal's response (NOW we're talking about Sal) Gotta say, I'm impressed all around. Makes me proud to own the knife and be a member here. NOT that I actually needed that to make me proud to own the knife, cause I've been playing with the knife for 3 days now and it stands on its own merits. Tight lockup, no play at all, smooth deployment (with a learning curve on fast deployment, I'm spoiled off my 'speedsafe' Leek) razor sharp out of the box. I took this sucker out and showed it off to a friend, day 2. 'Wait right there, let me show you something *seconds later I have the Endura and a piece of paper* You have to try this' ...I look at my knife (granted it's the ZDP-189 Endura, not the H1 Salt) and the quality and attention to detail that went into making a knife that is this perfect and I can't imagine that the same company would put out a knife that has the issues mentioned above.
My money is that it's an ebay knife that's very salt-like in appearance, and nothing more. There are a few 'how to spot counterfeit' topics on here that might be of particular relevance.
