Can’t here. I live in the desert corner of a county that has a larger city with a county sheriff who only signs for special need; general self-protection is not a valid reason for a permit.
I’m realizing that for the fortyish years I’ve almost always had a good knife in my pocket, I never had to draw it as a weapon. It helps that I avoid what i can only describe as harsh-vibe locales. Discretion and valor.
