I claim the ornamental design for the tomato tool, as shown and described.
FIG. 1 is a perspective view of the tomato tool, showing my new design.
FIG. 2 is a top view of the tomato tool.
FIG. 3 is a front view of the tomato tool.
FIG. 4 is a back view of the tomato tool.
FIG. 5 is a left side view of the tomato tool.
FIG. 6 is a right side view of the tomato tool; and,
FIG. 7 is a top perspective exploded view of the tomato knife, shown with a handle and blade separated from a sheath of the tomato knife. The blade extending from the handle is shown in phantom and forms no part of the claimed invention.
