Stanley 10-813 Quickslide Sport Knife;

Stanley 10-813 Quickslide 3 Sport Utility Knife features a sliding utility blade for precision cutting as well as a lock back sport knife for tough cutting jobs. The utility knife features a quick "no tools" blade change, allowing you to replace an old blade with any standard Stanley utility or hook blade. A patented interlock mechanism prevents both blades from being open at the same time. Cast zinc body for increased durability.
