Abstract: A portable martial arts device for rigidly holding one or more boards to receive a karate blow or the like. The device comprises a freestanding framework and a board holder mounted on the framework for rigidly holding parallel edge margins of one or more boards thereby to position the boards for receiving a karate blow or the like. A mechanism is provided for mounting the board holder on the framework for pivotal movement about a generally horizontal axis thereby to permit adjustment of the angular position of one or more boards in the holder. The framework is adapted for adjustment of the height of the board holder, thereby permitting adjustment of the height of boards in the holder.
