Abstract
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.
