Abstract
Abstract This invention provides a cutting tool, comprising a sleeve enclosing a suction chamber where, during use, a reduced pressure prevails and wherein a cutting member is arranged so as to be movable along a suction opening provided in the wall of the sleeve. The wall of the sleeve forms a light conductor. The sleeve can be tubular and is preferably manufactured from light conduction material, in particular glass.
