A shovel tooth includes a tooth holder having a front portion to receive a tooth cap, a rear portion having edges weldable to the inner surface of a shovel blade and a transverse web between the front and rear portions. A second rear portion, formed separately, is a hollow shell having edges weldable to the outer surface of the shovel and a front edge weldable to the web to permit the holder to be attached to blades of various thicknesses. The web can be concave and the front edges of the second rear portion convex to mate with the web. The blade can be notched.
