Cold Steel Spartan
This knife takes its inspiration from the Greek Kopis, sword of the hoplite warrior (think "300"). If you want a knife that you can carry in your pocket that will actually function as a self-defense weapon, this is a great choice.
The recurved 4 1/2" blade is honed to a razor's edge and its shape gives it the cutting power of a much larger blade. The unique thumb plate allows you to open the knife with one hand in the standard way, or you can catch it on the edge of your pocket as you draw it, easily rivaling the deployment speed of any switchblade. The unique handle wraps around your hand, protecting it and helping you maintain your grip whether you are slashing or stabbing. The blade is made of a high carbon stainless steel, hollow-ground and given a nice bead-blast finish.
Comes with ambidextrous pocket clips--although it is large, it is suprisingly comfortable riding in the front pocket, though it pretty much uses that pocket up. My martial arts Master bought one from me for his long walks home at night and says he has been quite impressed by it.
