Abstract: A hand tool for opening a paperboard carton having a push-in tab at a top corner. The tool has a generally spoon-shaped body with a bowl at one end of a handle and a bent arm extending from the handle in the same direction as the bowl and terminating in a free end more than half-way along the bowl toward its pointed distal end. The tool may be held upright, with the free end of its bent arm engaging the top of the carton and the distal end of its bowl engaging the pushed-in tab, and hen rocked to push in the tab. A projection on the inside of the bowl near its distal end is engageable with the push-in tab to pull it out when the tool is pulled away from the carton. The bowl has inclined opposite edges with teeth between its distal end and the free end of the arm for engaging the push-in tab.
