This video was originally posted by Christophe Scerri, COO, Persa Seguridad, Chile. It dispenses with all of the hokey knife fighting and hand-to-hand tactics; choosing instead to be grounded in reality. As you watch this short video, notice that at no-time does the operator close the assailant. Instead, the operator creates space and uses his support hand to block. The video is narrated in Spanish; judging by the accent I think it was filmed somewhere in Catalunya, Spain; probably Barcelona.
