Using the Klein D335-51/2C long needle-nose pliers is easy. For gripping thin wires, just place the wire between the finely knurled jaws and squeeze gently. The curved handles make it comfortable to hold and give you better control. When working in tight spaces, the long, narrow nose and slim hinge are your best friends. They can reach into areas where other tools can't. Remember, these pliers are made for thin wires. Don't try to use them on thick or hard materials as it may damage the jaws. After each use, wipe the pliers clean with a dry cloth to remove any dirt or debris. Keep them in a dry place to prevent rusting. The spring-loaded feature helps with quick and easy operation, but if it seems to be getting stuck, a little bit of lubricant can help keep it working smoothly.
