Tired of screwing things up? Perhaps it's time for a new screwdriver, or two. Screwdrivers today are stronger, safer and more useful than ever before. Gone are the days of bent shanks, broken handles, injured wrists and stripped heads. The basic screwdriver is composed of the head, handle, shank and tip. The two most important considerations in choosing a screwdriver are the material of which it is made and how the handle fits your hand. The handle must be shaped to allow you to apply as much torque as possible, based on your own strength. The shank should be constructed of forged steel -- it's the strongest. Also, a square shank can add to strength and allow a wrench to be used for greater power. Remember, a screwdriver is designed to install screws. Using the handle as a hammer can damage it, which can create a safety hazard. And that's the On The House tip for today.
