A device for destroying used tickets includes a housing and a cutter which is removably mounted to the housing. The cutter includes an enclosure having a slot which allows tickets to enter. The cutter also has a rotating blade which cuts the tickets as they pass through the slot. Both the slot and the blade are inclined relative to the horizontal, the inclinations of the slot and the blade being mutually opposite. Thus, the ticket is subjected to an effective angle of shear which is equal to the sum of the angles of inclination of the blade and the slot. The blade is in geared engagement with the same motor that operates a plurality of rollers for advancing the tickets through the device. The cutter enclosure is detachably mounted to the housing, so that it can be quickly and easily removed for servicing. The cutter effectively destroys the incoming tickets, preventing them from ever being re-used.
