Abstract
A shredder arrangement comprising a housing defining a feed slot for receiving sheet material inserted by a user; a cutting mechanism for shredding the sheet material inserted through the feed slot, and a protective guard for positioning across the feed slot to prevent relatively rigid sheet material from striking the user during shredding of such sheet material, the guard defining an aperture allowing said sheet material to be inserted through the guard and into the feed slot; wherein the protective guard is moveable between a first configuration and a second configuration to symmetrically adjust the size of the aperture.
