An example of a modern pyramid can be found in Paris, in front of the Louvre Museum.
The pyramid shape is alleged, among other things, to keep razor blades sharp and to prevent meat from decaying. Researchers adhering to strict scientific standards have not substantiated these claims.
When a Czech engineer, Karel Drbal, took a model pyramid to the patent office in Prague and told them it would sharpen blunt razor blades left under it, the staff refused to believe him. Only after their chief scientist tried it himself and found that it worked was Drbal's "invention" registered Patent No. 91304.
That was in 1959. But the idea was as old as the ancient Egyptians.
Drbal got his idea after reading about the experiments of a frenchman named Bovis who, on a visit to the Great Pyramid, found that small desert animals which had wandered into the pharaoh's chamber and died, yet had not decayed. Bovis wondered if it had been the pyramids themselves which had somehow preserved bodies so well, rather than the mummifications methods of the ancient Egyptians.
Bovis experimented with a scaled down model of the pyramid, placing inside it a number of highly perishable foods. They were preserved far beyond their usual life span, and he came to the conclusion that this must have something to do with the pyramid's actual shape. Hearing of Bovis experiments, Drbal wondered if the same principles might also apply to the corrosion in metal. Apparently they did, for out of the tests was born Patent No. 91304.
At one point there was a flourishing factory in Czechoslovakia, where razor blades were scarce, turning out plastic-foam models of the pyramids for sharpening blades.
Why they work and how they work, no one knows. A razor-blade edge is made of a fine layer of crystals- so fine that some believe that the mere pressure of moonlight can rub them off and blunt the blade- and it could be that the pyramid shape somehow focuses or concentrates energy on to them.
To test Drbal's sharpener, make a cardboard pyramid. The four sides should be 15.7 to 14.94 in whatever units of measurements are used. Fix the sides together with adhesive tape so the height of the pyramid is 10 units. Place the pyramid so that the base lines face magnetic north-south and east-west. Make a stand 3.33 units high (or a third up), and place it in the centre of the pyramid.The sharp edges of the razor blade should face east-west when placed on the stand. Keep the pyramid away from electrical equipment. The pyramid should also preserve perishable material such as meat or eggs, but only for a short while.
The hierarchical structures of some organizations are sometimes described as pyramids. This often includes sports league systems.
