FIG. 7 illustrates one example of a variety of configurations of the apertures 120 and cutting teeth 130. In the illustrated embodiment, each row R of cutting teeth aligns with apertures 120 of at least one adjacent row R of cutting teeth 130. For example, row R1 includes a single aperture 120a and single cutting tooth 130a. The cutting tooth 130a aligns horizontally with the two apertures 120 in the adjacent row R2. Said another way, the apertures 120 and cutting teeth 130 of one row overlaps the apertures 120 and cutting teeth 130 of an adjacent row. In this manner, the cutting teeth 130 in row R1 and row R2 cooperate to engage the surface that the back side 104 contacts to make efficient cuts of the tissue. FIG. 7 includes the same overlap and/or alignment for cutting teeth 130 in the other rows R1-n. FIG. 7 also illustrates that the apertures 120 of one row R overlap apertures 120 of an adjacent row R.
