Use a screw holding screwdriver to get screws started in awkward, hard-to-reach areas.
Use a stubby screwdriver in close quarters where a conventional screwdriver cannot be used.
A rounded tip should be redressed with a file; make sure edges are straight.
Screwdrivers used in the shop are best stored in a rack. This way, the proper selection of the right screwdriver can be quickly made.
Keep the screwdriver handle clean; a greasy handle is apt to cause accidents.
A screwdriver should never be used as pry bar. If it is overstressed in this manner, the blade might break and send a particle of steel into the operator's arm or even towards his eyes.

Don't use pliers on the handle of a screwdriver to get extra turning power. A wrench should only be used on the square shank or bolster of a screwdriver that is especially designed for that purpose.
Don't expose a screwdriver blade to excessive heat as it may reduce the hardness of the blade.
Don't use a screwdriver with a split or broken handle.
Don't use a regular screwdriver to check a storage battery or to determine if an electrical circuit is live.
