This is the gift your dad doesn’t know he wants until he gets it. We can tell because there are not many persons who imagine receiving a survival pen as a retirement gift. This, however, is a tactical pen and so makes for more of a survival tool than it does a pen. It can be a pen, a flashlight and even blade. If that isn’t surprising enough, this is one of the most durable pens in existence as it is comprised of aircraft grade aluminum. Now thanks to you, your dad is prepared for a tough day at retirement, or for battle.
