When you have a nail that is buried in the wood and you need to extract it without destroying the wood, this little nail puller is a great go to.Despite its small size, it can easily pull out a 5-inch nail. We love that it is small enough to fit in your tool belt and tool bag. If you find you need additional leverage to extract those long, buried nails, this is prepared to use a claw hammer to add extra leverage. The front left is spring loaded so it stays open until you begin to pry that nail out. Make for possible single handed use.
