Picture of a man with a comically-oversized novelty gun for comically-oversized novelty self-defense. This thread is not about tactical defense pens, but you can buy one at Amazon for tactical protection.
Amazon also sells war clubs.
Nobody ever suspects that your pen is really a tactical defense pen, and can be used in some manner for tactical defense. They also never suspect the war club. What I mean is that if I had a point, I forgot it.
