Abstract: A paper shredder for cutting sheet material includes a first and second blade and a sheet feeding assembly. The first blade has a cutting edge along one side thereof and the cutting edge has a non-straight profile. The second blade has a cutting edge that meshes with the cutting edge of the first blade and the first and second blades are movable relative to each other. The sheet feeding assembly moves the sheet material towards the first and second blade such that the direction of motion is generally orthogonal to each cutting edge. The cutting edge profile may have a variety of shapes, including a zig zag, a wave or a combination thereof. The paper shredder is used for making packing material that includes a plurality of pieces of shredded generally planar sheet material, each piece having two elongate outside edges with non-straight profiles.
