Using the Klein Tools 650 scratch awl is a breeze. When you need to scribe metal or start a screw hole, just hold the cushion - grip handle firmly. The hard - pointed tip makes it easy to mark or pierce surfaces. For punching jobs, apply steady pressure on the awl. Remember, always wear safety goggles to protect your eyes from any debris. After use, wipe the awl clean with a dry cloth to keep it in good condition. Store it in a dry place to prevent rust. If you notice any damage to the blade or shank, stop using it and get it checked or replaced.
