I claim the ornamental design for a foot rasp, as shown and described.
FIG. 1 is a perspective view of a foot rasp.
FIG. 2 is a side elevation view thereof. The opposite side view of FIG. 2 is a mirror image thereof.
FIG. 3 is a front elevation view thereof.
FIG. 4 is a bottom elevation view thereof.
FIG. 5 is a top elevation view thereof; and,
FIG. 6 is a back elevation view thereof.
The handle of the foot rasp contains inclusions of air bubbles. The size, number, shape and distribution of these bubbles is random and varies from foot rasp to foot rasp.
