Surprised no one has mentioned William Henry. I have 2" and 3.25" blade 'Attache' models. I carry the 2" one almost always as my 'sheeple' knife. ZDP blade still amazes me. Weight is 1.1 oz.
I also have an older ti-carbon model with pocket clip, liner lock, and 3.25" DLC-ed 154CM blade. I always carry that when jogging. Weight is 1.46 oz., and for some reason it even looks a lot smaller than it really is.
WH now offers the beautiful 'wave damascus' laminated w/ zdp, and now has a few models with pocket clips (they have largely gone to a 'clip-case'). I have drooled over the thought of getting one of these for jogging, but it's tough to justify $575 just to get the features of 2 knives that I already have combined into one, just to get a prettier blade. Plus I prefer liner locks, and WH no longer does them, so it would not be perfect anyway. Still....
