USGI Surplus Entrenching Tool (E-Tool) Shovel w/ Cover

The folding E-Tool.  An American military icon.  Is it the best in the world?  For tri-fold shovels that also work adequately as a pick -- it's the bestest-adequate shovel around.  Nothing can do as much and pack as small for as much abuse as they take.  

Real ones know it also works as a toilet seat for one cheek out in the field.
