A manually-operable shovel for efficiently moving material, including a shovel blade, a shovel handle, a joint for attaching the shovel blade to the shovel handle, and an articulation device cooperating with the joint for permitting the operator to position the blade to a predetermined fixed angle in relation to the direction of blade movement for moving the material in a predetermined desired relation to the direction of blade movement. The articulation device is moveable between an unlocked position wherein the angle of the blade in relation to the direction of blade movement is variable and a locked position wherein the angle of the blade is locked into a fixed angle in relation to the direction of blade movement. The articulation device automatically assumes the locked position during a forward, material engaging movement of the shovel and automatically assumes the unlocked position during a rearward material disengaging movement of the shovel.
