<p>A chalk stick holder, e.g. for writing on a blackboard, has a cylindrical shape with a hollow profile from one end. The hollow profile is provided with a slit end to enable a stick if chalk to be inserted and gripped. The user grips the slit end between thumb and fore- and middle fingers. The exposed length of chalk is easily adjusted by pulling the chalk stick into the required position without loosing grip. The holder can be made of any suitable material, e.g. wood.</p> |
