The Cangaceiro are a group of Brazilians who lives in the desert regions of Brazil.  These people are known for their use of knives in self defense and were nearly wiped out by the Brazilian Government during the 1950's.  Testa shows why they are referred to as the Desert Rattle Snake Knife Fighters Of Brazil.  The techniques range from stabbing to slashing, but are quite different from jungle knife fighting.  These techniques and combinations are lighting fast and the foot work accounts for only part of the reason.
