I claim the ornamental design for a utensil, as shown and described.
FIG. 1 is a front perspective view of the claimed utensil;
FIG. 2 is a rear perspective view thereof;
FIG. 3 is a front view thereof;
FIG. 4 is a rear view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is a left side view thereof;
FIG. 7 is a top view thereof; and,
FIG. 8 is a bottom view thereof.
The ornamental design which is claimed is shown in solid lines in the drawings. Broken lines of equal or substantially equal length dashes in the figures are for illustrative purposes only and form no part of the claimed design. Broken lines formed of unequal length dashes (i.e., dash-dot) show boundaries between claimed and unclaimed portions of the design. Oblique lines show a transparent, translucent, highly polished, or reflective surface, and not surface ornamentation.
