Arizona -- As we all know, a number of everyday items - and things you regularly carry on your person in particular - can come in handy in a self-defense situation. The unassuming pen is definitely on that short list of things you could potentially grab for if you ever found yourself in a tight spot.
So far, so good. Only problem is that most pens really don't stand much of anything before they break. Heck, a lot of them don't even function properly purely as writing tools...
Enter the Tactical Pens and similar special designed self-defense pens. These tools are - in addition to being pens (duh) - made to withstand serious abuse without splitting, bending or breaking.
The end to all your troubles? Well of course not. Like everything else they have their advantages and disadvantages, and you will of course be at least somewhat trained in the application. And also, keeping it in your purse or briefcase - you know the usual hiding place for your pepper spray canister - won't do you any good at all.
