ABSTRACT:
A shovel for digging narrow trenches, comprising a handle and a head, the head having at an upper end thereof a shank by which the head is secured to the handle and at a lower end thereof a blade which is slender and elongated and of generally U-shaped cross-sectional configuration. The blade is comprised by a bottom wall and side walls upstanding from the bottom wall. The side walls flare outwardly in the direction of the shank to form wings on opposite sides of the blade. The wings have bent-over portions serving as footrests for pressing the blade into the ground to dig a trench. The wings are so disposed as to bear on shoulders of a trench to serve as fulcra such that when the handle is depressed, the shovel will swing vertically about these fulcra and the blade will be raised. The blade is forwardly concave in a digging direction in a plane perpendicular to its cross section.
