The secret of our ratcheting screwdriver is the shape of the Beechwood Knob/Handle. It sits comfortably in the palm of your hand and allows a maximum amount of downward pressure on the bit without tiring your wrist. Almost all of your strength is available for the rotating task at hand (ratchet right or left). The Palm Driver comes with a useful selection of a dozen bits (Slot, Phillips, Pozidrive, Torx and Square Drive) but it will fit any standard 1/4" hex-shank bit. It’s a simple tool. Nothing fancy, but it’s a great value. Your wrists will thank you.
