A hammer is one of the most common tools around. However simple it is to use, certain safety precautions should always be taken when using this striking tool. Put on a pair of safety goggles. They’ll protect your eyes from any flying projectiles. The purpose of most hammers is to drive and remove nails. Using it for any other purpose will ultimately result in something bad. Only use the hammer’s head to strike an object, never the side, or handle. Improper use is the leading cause for a hammer breaking. Never use a hammer that has a damaged or cracked handle or chipped head.
