Abstract

A martial arts practice device (2) is provided for programmably simulating the breaking of a variably selective number of boards with actual breakage of smaller less costly slats (4, 76), but requiring comparable impact. A pair of hinged arms (16) and (18) mounted on a frame (6) have one or more slats (4, 76) mounted adjacently therebelow which are broken by the practitioner's impact on the top of the hinged arms (16 and 18). After breakage, the arms are pivoted back to a horizontal position and new slats are loaded for the next sequence.
