The 3 items I feel I could depend on to save my life if needed that I feel in my heart are 100% dependable are my Glock 26, as it is small, concealable, and dependable, the Randall Made knife I inherited from my father, who carried it strapped to his leg on every B-52 flight he ever made while defending his country against the Russian menace, and my reading glasses, as I can't see a damn thing without them. Without them, everything else is pointless.
