    Abstract: A sawhorse of the folding leg type, characterized by having three sets of outwardly folding legs that are held in the open position by three pairs of attached braces, that in turn are attached to a bar that runs parallel to the beam of the sawhorse, which bar allows a user to simultaneously open or close the braces and in turn open and close the legs of the sawhorse. The sawhorse is further characterized in that, once the braces are opened and locked, the sawhorse can be turned onto a side or either end, so as to support downward-bearing loads in any one of these orientations.
