I've taken a quick look at my current set of folders, and none of them fit the bill as a knife that can be used for self defense.
I'm perfectly aware that a folding knife is hardly a prime choice over a fixed blade, but it's really the only viable option for me as:
1) I doubt I can carry a fixed blade in my pocket all the time.
2) I'm pretty sure that hanging a knife in a sheath from your belt is just begging for you to be arrested or to have the knife stolen and used against you. Thus, concealment is the only option.
I'm going to take a few stabs at the ideal properties of a good defensive folder, and I invite anyone to correct me if I'm wrong(or debate your point).
Handle Grip-
I believe the scales on my Endura fits the bill perfectly for maintaining a firm grip on the knife during combat. My BM 943 and Kershaw Shallot handles are far too smooth to be practical in live combat. A rubber handle would be nothing short of perfect, but I don't really see those on a folder.
Blade Geometry-
I believe a thick and wide blade with a saber grind would be best, as a full flat grind blade is more than likely to be snapped off. Edge bevel should probably be 25+ degrees per side for added toughness. It wouldn't do well if the knife only cut once before breaking off. This is why I can't consider my Endura as a defensive option, as the flat ground blade is too thin for a rough fight.
Edge Detail-
I'm not entirely certain, but I believe a full plain edge is best for combat. It's been stated that a serrated edge will "catch" on clothing, whereas a plain edge will cut straight through. Combo-edges are IMO, simply to intimidate while hampering the function of the knife.
Lock-
I believe the back lock will provide the sturdiest lock on the blade.
Steel-
I believe D2, M4, M2, or any other tool steel with high strength and toughness(more toughness than strength) is key. Corrosion resistance should be more or less irrelevant, as rust will be the last thing you're worried about in a combat situation. You also don't want the blade to chip or break off.
Opening Mechanism-
The spyderco round hole doesn't quite seem to compare with the thumb studs on my BM 943. It could simply be the tight screw though. The Speed Safe on my Kershaw is cool and all, but I still feel that my 943 is my fastest opening knife(though it wiggles). An automatic knife would be best, but there's a bit of legality issues surrounding that type of opening mechanism.
Based on these considerations, I believe the Benchmade 913 and Spyderco Military or Police models best fit what I'm looking for. Though Benchmade for me has had a slightly sloppy fit and finish(blade wiggles when loose, yet when tightened enough to stop the wiggling, the knife becomes impossible to open. There is no "sweet spot" and lubing the knife more doesn't help). The Spyderco knives don't have the tougher tool steel in their line of Military or Police models.
I've also had my eye on the Spyderco Scorpius, which doesn't have handle scales or the plain edge I'm shooting for, but the wavy contours on the handle allows you to get a tighter grip on the knife. The end of the handle is also perfectly shaped for a sharp non-lethal blow. Though I'm questioning the wisdom in getting drawn even an inch closer to combat due to the handle and 3 inch blade.
