Abstract: An upper plate is spaced from a lower plate by a gap. Teeth extend from a lower surface of the upper plate toward the lower plate. The gap between the upper plate and the lower plate has a first size larger than a second size with the gap adjustable in height between the first size and the second size. Media storage items can be placed within the gap. A compression force is applied to move the plates toward each other and drive the teeth into the item. Preferably, relief holes are provided in the lower plate aligned with the teeth extending from the upper plate so that the teeth can entirely penetrate the item to be destroyed within the gap. Preferably, teeth also extend up from the lower plate. Guards associated with each plate sheath the teeth until the teeth extend into the gap for item destruction.
