I just use my edger for edging the lawn by the sidewalk and driveway. This blade does NOT edge straight. It CHOPS and MUTILATES the grass instead of leaving a smooth straight line. Having gone from a straight edge blade to this blade was a HUGE downgrade as far as the quality of the cut goes. Also, the blade is short, and I have to put the edger on the lowest setting in order to get into the dirt where some grass is below the surface. Granted maybe this works best for digging or trenching but the blade is horrible, IMO, for straight edges.
