Paragraph Number

77

In one embodiment, a plurality of cutting teeth 230 may be connected to the back side 204. In one embodiment, each cutting tooth 230 includes a cutting edge 232 oriented, or directed, toward a common side. In one embodiment, the common side is the right side 210. In another embodiment, the common side is the left side 212. Having the cutting edge 232 of each cutting tooth 230 directed towards a single side, the common side means that the cutting teeth 230 will cut in a single direction. If the cutting edge 232 of each cutting tooth 230 is directed towards the right side 210, the cutting teeth 230 will cut when the cutting teeth 230 are moved in the direction of the right side 210. If the cutting edge 232 of each cutting tooth 230 is directed towards the left side 212, the cutting teeth 230 will cut when the cutting teeth 230 are moved in the direction of the left side 212.
