This is a handy man's tool, a pocket Phillips screw driver with bonus functions. It's meant to be in the bottom of a pocket, laying in wait, for when you need it. The integrated Philips is the most handy and useful tool tip, there are so many things with a Philips head screw holding you back from accessing a panel or changing your kid's toy batteries. So it's a serious time saver! The internal storage slot is designed to fit either an extended 2"(50mm) hex bit or 2 pcs of 1"(25mm) bits, this is handy for those bits that are unique to your needs. The 6 o-rings are carefully placed to capture the buts, while also offering bit retention. The o-rings also give the handle a round driver like feel to aid in classic Phillips screwdriver rotations, the pronged pry stud extensions offer additional leverage to torque screws tight or loose.
