Mjolnir

Inspired by and named after the original silhouette of Thor's hammer from Norse mythology (not the comic book version!) these hammers are designed to concentrate force into a small surface area for deep tissue thud ranging from a massage-like sensation, all the way through severe stomping, with minimal effort on the part of the top. Due to their engineered balance and weight ratios, these can be wielded with authority without strain. Add interlocking-block-style pegs to one side for even more severe sensations.
