Is there anything in the world as useful -- as essential -- as a pair of sawhorses? Short of sprouting a second and then a third set of hands, buying these is probably the best thing you can do to improve your life. Seriously.
These classic horses have a wide top made from a 2x6. So, in addition to holding whatever you're working on, they can also serve as a kind of field workbench.
There's also a handy tray, for your tape measure, square, and other essentials. The full-width tray is large enough to hold many handsaws, or even a cordless Skil-saw (see photo). Yet, it is not so large as to stop you from stacking the horses neatly when not in use.
