Using the DeWalt Offset Right Cut Aviation Snip is easy. First, make sure you've got a good grip on the snip with its slip - resistant cushion. Line up the material you want to cut along the serrated blade. Then, simply squeeze the handles to start cutting. When cutting sheet metal, take your time and follow a straight line for the best results. As for safety, always wear safety goggles to protect your eyes from any flying debris. Also, keep your fingers away from the cutting edge. To maintain this tool, after each use, wipe it down with a dry cloth to remove any dirt or debris. You can also apply a light coat of oil to the blade to prevent rusting. Store it in a dry place to keep it in good condition for a long time.
