Listing the basics of hand tool safety is easy: make sure the tools are in good condition; match the tool to the job; never force a tool. Using the rules is more difficult. But take a moment to follow the basics. Being a craftsman means taking your job seriously. Because construction is rated as the most dangerous industry by the National Institute of Occupational Safety and Health, it should be treated as such. Mistakes in using hand tools can be costly, especially because many injuries involve the eyes. Most accidents can be avoided by using what you know.
