Abstract: A type of stapler has a handle that permits it to be used like a hammer. The end of the handle is modified to permit it to receive the body of a utility knife. The latter is retained within the handle by a screw that replaces the screw which previously held the halves of the utility knife together. The blade-retracting lever of the utility knife is made accessible on the upper portion of the handle. The blade of the utility knife can be extended and retracted at the end of the tool opposite the staple-dispensing end of the stapler. The handle of the stapler serves as the handle of the utility knife. The tool thus formed is useful to persons who work with sheets of material that must be stapled to an underlying structure then trimmed to the shape of the structure and/or cut free from a roll of sheet material.
