An snow removal tool having an insert-molded wearstrip is disclosed. According to one embodiment of the present invention, the tool includes: a plastic blade portion and a wearstrip attached to each other by insert molding. Insert molding is performed by placing the wearstrip, which has one or more openings therethrough, in a recess of a mold cavity. Plastic is injected into the mold cavity and flows through the openings in the wearstrip. Upon solidification of the plastic, the final molded product has a cutting edge of the wearstrip protruding from a front edge of said snowtool. Preferably the wearstrip is made from galvanized steel and has a fold or ridge across it to increase stiffness of said snowtool in bending.
