One can buy a "Rambo" or Ka-Bar type survival knife of questionable quality in many convenience stores, pawn shops, "outdoor" stores etc all around the Country.
I might not want one for true survival purposes, but if one was used it appears to have been somewhat functional.,
The desert is a true treasure for him who seeks refuge from men and the evil of men. In it is contentment In it is death and all you seek (Quoted from "The Bleeding of the Stone" Ibrahim Al-Koni)
