Using the DeWalt DWHT14679 Offset Center Cut Aviation Snip is easy. First, make sure you've got a good grip on the tool with the slip - resistant cushion grip. Place the material you want to cut between the blades. The serrated cutting edge will hold the material in place so it won't slip. Then, just squeeze the handles to make your cut. When using it, avoid cutting materials that are thicker than 18 - 22 gauge sheet metal as it may damage the tool. After each use, wipe the blades clean with a dry cloth to prevent rust. You can also apply a little bit of oil to the moving parts to keep them working smoothly. Store the snip in a dry place to keep it in good condition.
