ABSTRACT:
This manufacture is a sawhorse, so designed that one will perform tasks that are difficult, if not impossible, with two traditional sawhorses.
Parallel but separated backs support wide materials for sawing, cutting, or drilling. Narrow materials are supported by the legs and contained between the backs. Kerfs in the backs are aligned to permit forty-five and ninety degree cuts when the backs are used as a miter box. The legs are constructed to hold tools used in the construction process. The sawhorse assembles and disassembles without tools, and it stores and transports flat.
