MecArmy’s SK3FT Titanium Tactical Ring has a tungsten steel bezel that can break glass and is ideal for self-defense. It also has a built-in bottle opener at the back. You can also order it with a glow-in-the-dark bar.
A pen that’s ready to come to your aid, whether through written word or action, the Double Duty Tactical Pen 1.5 offers both a Fisher Space Pen tip for writing, and sharp point for self-defense. Made from machined aluminum, with a knurled grip that works for holding either tool.
