Abstract
This invention relates to utility knives used to cut various items, including cartons, cardboard, string and wallpaper. Specifically, the invention provides a disposable one-piece razor blade utility knife in which the blade is adjustable yet permanently affixed to the knife handle. When the complementary shells of the handle are open, the blade may be placed in a usable position in which the cutting edge will protrude out of the handle when the shells of the knife are later closed or in a safety position in which the blade will be fully retained in the handle when the knife is closed.
