How to use adjustable wrenches; "Crescent" wrenches

If you must use an adjustable wrench do it correctly. Push toward the adjustable jaw. Pushing towards the adjustable jaw reduces the changes of slipping and damaging your fasteners and/or your knuckles. Please don't call them "Crescent" wrenches, unless also call all combination wrenches "PLOMB" wrenches.
