A trusty tool for all trades - up for any task! The SlidePro Locking Utility Knife has a wiper that removes excess dirt and helps protect the blade. It works with most standard snap-off blades and is a simple, tool-free blade changer. A safety lock prevents accidents so anyone can safely tackle home improvement projects. Add a wrist strap or lanyard through the hang hole. The blade storage compartment holds up to 3 strips of 7 snap-off blades.
