It’s a simple but effective little tool. I have one on a s-biner with a small flashlight and a small titanium carabiner that has a tiny reversible Phillips and flat head screwdriver. Also with small replaceable razor blade. Clipped to a Bone Tactical Big Nasty, I have a self defense tool as well as EDC items that are easy to grab in a hurry. Also large double ended screwdriver bit on the Big Nasty gives more tool options. Really handy at work,with piece of mind for less lethal.
