A tool for cutting open the tops of containers having beaded tops has first and second levers pivotally connected near one end with a first spring holding ends of the levers apart. A knife with curved and straight opposite sides is carried on the first lever which has two pivotally attached sections. The second lever has a fixed first jaw and carries a spring biased pivotable lever formed with a second jaw having a projecting tooth, which engages under the bead of a container and holds the second lever stationary, while the first lever draws the knife along the top of the container cutting the top and forming a peripheral turned up lip in the cut top.
