    Abstract: A foldable sawhorse that can be shipped and stored in a small volume. The sawhorse comprises first and second leg assemblies and a plurality of spacing members. The leg assemblies are preassembled at the factory. The spacing members are bolted onto the leg assemblies by the end user. Hinges are formed by tubular hinge members attached to the upper ends of the leg members; the hinge members are either nested one within the other to form the hinge assembly, or separate pin members can be provided that extend through two hinge members. The sawhorse is inexpensive to manufacture and ship but sturdy and flexible in use.
