a foldable sawhorse comprising first and second leg structures each having a hinge member integrally formed therewith . one of these hinge members is an outer hinge member having a passageway extending therethrough . the other hinge member is an inner hinge member adapted to extend through the passageway in a way that allows the leg structures to rotate relative to each other about a pivot axis . an engaging member is attached to the outer hinge member such that , when the sawhorse is in use , the engaging member is appropriate for engaging a workpiece or other surface to be supported . the hinge members as described above engage each other in a manner that creates a very strong and durable pivot or hinge mechanism . locking assemblies are employed to fix the sawhorse in an open configuration and allow it to be closed into a closed configuration for storage .
