The Craftsman All-In-One™ screwdriver stores six blades permanently, eliminating lost blades, says the company. Each full-size blade is stored in its own chamber until the technician wants to use it. Then the tech rotates the selector ring until the blade aligns with the arrow, slides forward, and clicks into place in the magnetic chuck. The screwdriver includes 1/8-, 3/16-, and 1/4-in. slotted blades and #1, #2, and #3 Phillips head blades.
