ABSTRACT:
A breakaway board for practicing chops and kicks in karate and other martial arts improves upon the prior an by increasing control over the board by the board holder. The paired mortise- and-tenon interlock between the two breakaway halves is modified by including a detent in one or more of the pairs between mortise and tenon such that the two halves definitively snap into place when they are reassembled so that the person holding the board can be assured that the two halves are fully together. Additional protection for the board holder is provided by an improved palm pad to prevent bruising after repeated strikes, and to accommodate board holding handles, the front faces of the two halves are grooved at the top and bottom edges to provide a positive seat for the resilient cord characteristic of these board holders.
