I'm an owner of many of these knives being mentioned here (ZT's, Emersons and CRK's). I personally wouldn't pay Emerson-level pricing for a ZT, I just don't get the enjoyment factor out of ZT ownership that I do with Emersons. That is not a comment directed at the intrinsic value of the two knives, but for me an Emerson brings me considerably more joy than a ZT, which in a nutshell is why I am a knife zealot.
Wow that's actually cool of you to say, because I think many would say the opposite, but you are honest and say your enjoyment trumps factors that are usually pointed out.
IIRC too you also had a time where you weren't fond of Emerson? By no means calling you out, and I might be confusing you for another user, but point is we are allowed to change how we feel about a knife and/or maker.
