[origin: WO9117694A1] A mechanical lead pencil having the capability of feeding different diameter leads. A first collet (21) is disposed in the pencil barrel (12) for feeding the lead (20) and a second collet (25) is located at the barrel open end for retaining the lead (20) during use of the pencil. An elastomeric disc (35) is provided between the two collets (21, 25), having a variable diameter opening (38) at the center thereof for frictionally engaging the lead (20) and preventing its release when the two collets (21, 25) are in the open position.
