I've looked around a lot for basically the exact same knife as you. Tip-up, good steel (better than AUS6/8 like with Kershaw/Cold Steel), preferably a metal handle, tightenable blade pivot (vs. riveted which gets loose and you can't do anything about it), tough steel that'll get sharp and stay that way.
I prefer a tanto point, like my CS Voyager, as the two fairly straight edges are more useful to me than a clip point, or curved blade.
Spyderco: There are a few models I like, but they often have tip-down carry (STUPID, imho), and I like a thumbstud vs. a sypderhole (a topic debated here a lot). I like something that'll ride well in my pocket, which is not always a Spyder, b/c the hole makes those blades so tall they take up a lot of room folded up.
Benchmade: Probably the way to go here. They make many models in good steel (D2 options on many of them). I'm not a fan of their styles usually, though, and 154CM is kinda "OK" steel nowadays of CPM-3V and S30V. Though some models are nice, like the 732 and 943: Their clips facing the right way

.
Others: I think you might want to out of the box. Though I hate the liner-lock (Walker lock) as it tends to jam, there are a few I really like.
Al Mar SERE 2000 (highly adored around here)
Al Mar Shrike (also available with G10 handles)
Seki-Cut Encounter (I've heard nothing but good stuff about this one, also available at AG Russell)
Camillus: The EDC and Dominator are really nice, now available in really nice steels, but the clip is ugly, huge, and annoyingly tip-down. The MAXX is a nice large knife which I've considered.
SOG: Mostly AUS8, probably not what you're looking for either.
Microtech: Their non-auto knives are popular, high quality, and worth consideration. This just might be my next EDC, if not the Seki-Cut above.
Buck: The
TNT and friends is popular, but I don't really like framelock and it's tip-down again. Their
Strider coop knivers are nice too. Clips are tip-up, which is nice.
That oughta get you on your way. Check out
AG Russell's site, too. They've probably got like 50 knives that'd work for you. Fun to look through it all.
Right now my EDC is a CS Voyager, which is actually just what I need. It's a little sloppy after 2 years, but the steel's sharp and stays that way (will stay semi-shaving sharp) for a week or so of hard use which is good enough for me. Great blade, thumbstud, and best pocket clip I've found yet. Light, comfy but big enough for big jobs and self defense. If it ever does give out or get lost, I'm gettin one of the ones I talked about above.
Sorry for all the reading material, good luck!

EDIT: If you don't make it all the way through all that, it should at least illustrate you've got a lot of options! Most steel will be good enough for you, so look at grip shape/material, blade shape, lock type, and clip type before you check whether it's S30V, D2, or whatever.
