    Watchmakers screwdrivers come in sets of various different sizes. Choosing a suitable size for the screw you wish to loosen, or tighten, will reduce the risk of damaging the screw head or slot. You should choose a screwdriver with a blade width slightly smaller than the diameter of the screw head. If the blade is to large then you risk damaging, or scoring the material around the screw. If the blade is too small then the screwdriver may slip out of the slot and scratch the surrounding area. Also, if the blade is too small then you may not get enough torque to loosen or tighten the screw properly.
