i can carry folders concealed, but never consider my knife a self defense weapon unless, like pitman, i'm in the woods and it is animals i'm concerned about. at any rate, around town, i have mostly been carrying my bradley alias 1, but also carry my protech runt, an older benchmade, or my spyderco walker. when hiking or camping, i always take a fixed blade, or two, along with a folder and a multitool. but again, self defense isn't my goal, but i do realize that i have something on me that can cause great bodily harm, and i respect it as such, and hope that i never find myself in a situation where i am faced with the decision to cut or not to cut a person.
