I remember reading a while back, possibly in Cosmic Trigger or some other such book, that the pyramid shape is naturally conducive to the sharpening of blades. According to this source, if you put dull blades inside a pyramid-shaped object, they will naturally sharpen over time. I don't think it matters what material the pyramid is made from, or how big it is. Anyway, as implausible as this idea seems, I know that I've heard it at least a few times, and cannot find anything about it on Snopes. So my question to the MeFi Mythbusters- real or urban legend?
