I would say there are 2 kinds of hype, the first and objectionable one is where the maker/company markets the knife in a way as to, well, hype it, extolling its miraculous advantages and such, and that its made, of course, for honest to god Navy SEALS...

but then, there's the hype that surrounds a knife, but its from people who own the knife in question, obviously this hype is prevelant here in the forums, and this type of hype is different, because, its not actually hype, but the experiences and evaluations of actual owners and shouldnt be discounted the way advertising (false) hype is.
Best example is when someone begins a thread on the Sebenza and some people will inevitably chime in that theres too much "hype" surrounding the knife, well, no, thats not really hype, since its generally the praise of actual customers who love it so much, they cant resist the urge to "hype" their favorite knife, and this is as it should be, and this type of talk does influence me to some degree, so, definitely discount false advertising hype, which is easy enough to recognize, but i listen to some extent to what others think about the knife they own and like, if you want to discount that as hype too, that's your choice, but i see it differently.
If the "hype" that surrounds the Sebenza is based in its quality and thus is deserved, then its not really hype is it, at least not in the perjorative sense of the word.
