ScrewdriversNever use a screwdriver as a cold chisel, or for prying, punching, chiseling, scoring or scraping.

Make sure the tip fits the slot of the screw; not too loose or tight.

Never expose a screwdriver to excessive heat or cold.

Always discard a screwdriver with a worn or broken handle.

Never use a screwdriver on a workpiece held in your hand. A slip could cause serious injury.

Never depend on a screwdrivers' handle or covered blade to insulate you from electricity.

Vinyl covered blades are intended only as a protective measure against shorting out components.
