Abstract

A dart sharpener has a guide 36 to receive the dart point which is to be sharpened and this is carried at one end of a rotatable member 34 journalled on a spindle 32 of a crank 30 of a spindle 14. The said end of the member 34 is slidably connected to one end of another member 16 which carries an abrasive surface 24 and is journalled on the spindle 14 so that, in rotation of the whole, the guide reciprocates relative to the abrasive pad and sharpens the dart. <IMAGE>
