La Double Canne (double cane French stickfighting).
"La Double Canne" is becoming more and more popular in the French Savate and associate sports (La Canne/Le Batôn) world.
Created in 2009 by the ASCA federation, it has become a part of the CNCCB (Comité National de Canne de Combat et Baton) since this year.
