FIG. 2 is a top front left side view thereof.

FIG. 3 is a back top right view thereof.

FIG. 4 is a front top right view thereof.

FIG. 8 is a close up right side view thereof; and,

FIG. 9 is an expanded fragmentary view of the call-out location shown in FIG. 2.

The broken line elements are included for the purposes of illustrating portions of the microtrencher blade and form no part of the claimed design. The line indicated by alternating dot-dash is a boundary line, the interior of which does not form any part of the claimed design. FIGS. 1, 2 and 5 represent callout locations for the expanded fragmentary views shown therein, with the borders of the call-out locations shown by lines of alternating lengths. Lines included with thin weight and which do not extend to any adjacent line are provided to show contour.
