The rotatable socket member includes a tubular insert to rotatably seat in the permanently mounted socket of the shovel blade, a first tubular socket to receive the end of the shovel handle in axial alignment with the tubular insert of the socket member, and a second tubular socket for receiving the end of the shovel handle which extends at an oblique angle from the longitudinal axis of the tubular insert portion of the socket member. The socket member in accordance with this invention permits positioning the shovel blade at different angles to the shovel handle, both vertically and horizontally. | ||||||
