A few suggestions that immediately come to mind from my collection:
Real Steel Megalodon (3.875") M390 Ti/Ti
Hinderer XM-24 (4.00") G10/Ti M390
ZT-0452 (4.10") CF/Ti S35VN (and the G10/Ti GLD and CF/Ti BLU which are both M390 Sprints)
ZT-0560 (3.75") G10/Ti Elmax
--------------------------------
The Megalodon is my favorite as an EDC and is the "best buy" IMO. Versatile drop point blade shape, relatively light weight and slim profile.
The 0452 is my favorite for "style." Easy to pocket but not well suited as a general EDC due to it's straight spear-like blade but, then again, that's what makes it look cool.
I only own the 3 variations mentioned but there are at least 3 others that I can think of off-hand, including a plain Ti/Ti, blue Ti/Ti and Glow/Ti that I think all use S35VN steel like the basic CF/Ti model which do/did not appeal to me but may appeal to others.
The Hinderer and 0560 are both impressive for their bulk/size. Real workhorses if you actually intend to "use" them but not something you'd want to carry in your pocket much as an EDC due to their size/weight.
