i've got expensive knifes but i don't edc them...only when i carry a backpack or fatboy, i have a rescue blur available, and i don't advertise that fact to anyone either...otherwise it's just the little swiss card blade in wallet and occasionally a chive...
i don't kid myself; i don't work and i don't put myself in situations (and i avoid situations) where i might have to cut someone, so i don't carry a "tactical"...if i did find myself in a situation, i'd improvise (which i have done before).
