I've been tempted to try one of the Navy FFG K631's. They resemble a Spyderco.
I have a couple of black 710s. Great knife if you don't mind tip down carry.
I picked up the BM Mini-ambush a few years ago. I was carrying it all the time until I found the smaller, more office friendly 763.
The 763's hook shaped tang also serves as a good bottle opener. I initially thought this would snag in the pocket, but it hasn't bothered me. I probably sound like a commercial...
The Gerber EZ-out is also a great knife. Wish the steel held an edge better, but they fit the hand well. SMKW had these dirt cheap a while back in a camo pattern. They used to make a version with the ATS-34 steel. I'll find a deal on EBay one of these days.
