After having tried several different EDCs, all folders (Native, Junkyard Dog II, Dragonfly, carried a PT CC for a little, other various Spyderco's) I stumbled upon the 350. Hadn't really paid much attention to ZT's as I do think the 300's are a little too big/heavy/bulky to get away with carry in an office (and don't even think about pulling it out in front of someone) but I'm glad I decided to check back.
The 350 is about as close as I've found to my ideal EDC: Offers tip up carry, discrete clip, flat ground blade, thick enough tip to do some prying, good steel (s30v is good, would have preferred a d2 though), thick liners which i prefer over a frame lock (aesthetically and structurally) and most of all a good size. Small enough to carry comfortably and use without drawing attention, big enough to do what you need and God help you defend yourself if need be. Everyone thinks this is a huge blade but only because it's got a nice wide blade and performs like a bigger knife. Really, it's smaller than the Junkyard Dog II and just a hair bigger than the native. Most importantly, it's around $100!!! Let's be honest, if you going to spend more than a hundred bucks on a knife, it better be a fixed blade or gun.
Yes there are better knives out there. I'm was a big Spyderco fan and to be honest if I could find a Paramilitary in D2 I'd grab it, but in Spydercos infinite wisdom they only made a sprint run, just like all they're good knives. Also, they only make a handful of styles in the US and I think I'm done supporting a company that makes most it's money from asian stuff. Striders, Emerson, CRK are awesome too, but like I said, I'm not paying 300+ for a folder.
