It was great to have Sensei Clinton visit our dojo in Somerset West and share some of his thoughts on knife defences. As an ex-police officer he has had first hand opportunity to see what works and what doesn’t. One of the most important lessons was how an attacker from region or culture attacks very differently than an attacker from another culture, and how knife attacks (shanking) in the prisons cannot be translated as a template for what happens in the street.
