The title says it all. A solid duty pen at a much better price point than most of the other options out there. The screw driver offers quite a bit of versatility in the field, and at home. I used it to tighten a seal on my air intake so I could limp the car to a mechanics shop not too long ago, because I almost always carry a pen, but leave my tool bag at home. My best friend also uses it as a Search Tool in lieu of a Kubaton while working security. I've put my TacTool through quite a bit of abuse. I can say from experience that this knife will survive anything short of literally running over it with a 15 thousand pound ambulance. A great tool to add to your kit, and given the amount of dollar store pens I break or lose in a day, it's paid for itself two times over.
