I claim the ornamental design for a cleaning tool blade, as shown and described.
FIG. 1 is a perspective view of a cleaning tool blade.
FIG. 2 is a front view of the cleaning tool blade.
FIG. 3 is a back view of the cleaning tool blade.
FIG. 4 is a right side view of the cleaning tool blade.
FIG. 5 is a left side view of the cleaning tool blade.
FIG. 6 is a top view of the cleaning tool blade; and,
FIG. 7 is a bottom view of the cleaning tool blade.
Portions of FIGS. 1-7 are shaded with substantially parallel and non-oblique lines to show surfaces that are less smooth and reflective than portions of FIGS. 1-7 that are shaded with oblique lines.
Any features in FIGS. 1-7 shown in broken lines form no part of the claimed design of this Application.
