I carry a Spyderco folder all the time but it's used as a screwdriver/all purpose tool more than anything.

If I were geared up for possible trouble I have a few straight knives. I do that for hiking/camping mostly since I don't frequent bad neihborhoods much these days.

Other than where you're pulling from a gun and knife are probably about the same (if you can pull one safely you can pull the other just as easy).

Suggestions on CMA empty hand styles to augment weapons carry? Short hand styles (Wing Chun, Bak Mei, etc) or Eagle Claw, CLF etc.?
