The conical fastening device (1) consists of a gently tapering cone (3) made of metal especially aluminum. It has three shallow equally spaced longitudinal grooves (7-7'') with straight sides. The grooves are separated by broad conically tapered areas (5). A through bore (9) near the broad end of one of these areas accommodates a nail which can extend into a conical blind bore (13) which may hold the end of the wooden stick.
