发明名称 Methods and apparatus for drywall tools
摘要 The present invention is directed generally to building tools that are high quality, durable, and in some case lightweight. Various tools may be made, at least in part, using a material including magnesium to reduce the weight of the tool. For example, a trowel includes a tang, support member or attachment member that may be made, at least in part, of a magnesium material so as to create a more light weight trowel. The tang, support member or attachment member connects the trowel handle to the trowel blade. The trowel blade may be made of a steel material or a high carbon steel material for high durability. The trowel may be, for example, a concrete trowel including a cross-ground trowel, a flat back end finishing trowel, or a round/round finishing trowel.
