摘要：
The upper and lower end portions of a karate practice board are adapted to be clamped by upper and lower hand-held holders. Each holder includes an elastic tube for clamping the adjacent end portion of the board and further includes a U-shaped guard. When the board breaks, the guards of the holders reduce the danger of injury to the hand of the person or persons holding the holders.
