Abstract: An opener apparatus for beverage cans having an opener tab provided on the top wall includes an elongated tool having a hook portion at the forward end and a handle portion at the rearward end. The hook portion extends forwardly from the handle portion a and then downwardly and rearwardly to define a channel adapted to receive the opener tab for lifting the tab and opening the can in response to lifting movement of the tool when a force is applied to the handle portion. A leg member may be extended downwardly from the tool and positioned for simultaneously depressing the scored section of the can top wall into the can and providing a fulcrum for lifting movement of the hook portion in response to downward movement of the handle portion.
