Paragraph Number

49

In one embodiment, the cutting tooth 130 may extend from the back side 104. In one embodiment, each cutting tooth 130 includes a cutting edge 132 oriented, or directed, toward one of the right side 110 and the left side 112. Having the cutting edge 132 of each cutting tooth 130 directed towards a single side, either a right side 110 or a left side 112 means that the cutting teeth 130 will cut in a single direction. If the cutting edge 132 of each cutting tooth 130 is directed towards the right side 110, the cutting teeth 130 will cut when the cutting teeth 130 are moved in the direction of the right side 110. If the cutting edge 132 of each cutting tooth 130 is directed towards the left side 112, the cutting teeth 130 will cut when the cutting teeth 130 are moved in the direction of the left side 112.
