Pyramids (flat sided, like the Egyptian pyramids) and
Cones (like an old fashioned ice cream cone with the top and bottom cut off
square) in several sizes are used for a multitude of purposes.
They may be a convenient shape and size, with large surface areas for easy melt
down or used as a heavy tumble and debur media, as an example.
Whatever your need them for, why not consider Materials Management, Inc. as your
source?
