No, this was not invented by an Egyptian; however, we woodworkers are beholden to them, because they invented PLYWOOD. The pyramid is designed to hold a set of wrenches, be it a set of box, open-end, or combination wrenches. The photo shows a set of 10 wrenches, but it can be made to accomodate any number. I gave pyramids to two of my grease monkey ( mechanic ) friends; they like them and set them up in their shops. The wrench size can be written in above the wrench, and it can be mounted on pegboard. Makes a nice caddy for daddy if he likes to work on things.
