JohnWEIt's actually nowhere near being a Kubaton, if you look at its dimensions. The diameter of each is less than that of a pencil, and neither is longer than 3.5 inches. I wouldn't want to rely on anything that small to do more than maybe STAB them in the pressure point. I have pens for that if that's the goal. I'd rather see these as convenient measurement tools over potential defensive weapons. Being made of titanium is purposed more for 'convenience of carry' EDC weight over 'weaponized durability' in its design. Seems they'd have made them thicker if that was the intent. Just my $.02. Either way, despite the other comment, I NEED THESE. :)
