Deucedly clever of those chaps to devise such a multi-purpose tool. What they failed to illustrate was how good it would be at chopping off heads. The Russian SPETNAZ are past masters of using an E-tool as a weapon.
But "seriousnously" now, I do keep a U.S. made folding E-tool in my RAV 4 for digging out in winter or in the desert outback. Used it several times in the winter and was glad I had it.
