Using this Klein Tools pocket knife is straightforward. To open it, simply flip the blade out until it locks in place with the liner lock. This lock ensures the blade stays open during use, keeping you safe. When you're done, push the liner to release the blade and fold it back in. For skinning small wire and cable, place the blade against the wire's insulation and gently cut through it. As for maintenance, keep the blade clean after each use. You can wipe it with a dry cloth to remove any dirt or debris. Every now and then, apply a small amount of oil to the blade to prevent rust. Store the knife in a dry place when not in use. And always be careful when handling the sharp blade to avoid any injuries.
