Abstract: First and second levers are pivotally connected together at one end and have opposed portions provided with one or more cross grooves for receiving nuts to be cracked. These grooves have varying depth from one end to the other and also have varying width, thus accommodating a wide range of nut sizes. The grooves also have transverse ribs to hold nuts in place while being cracked. In a preferred structure, the grooves are defined by straight wall segments meeting in angular relation. One of the levers may comprise a base portion for seated support on a supporting surface, and the other lever may comprise a handle for applying leverage.
