Many would argue the use of any weapons when it comes to self-defence, and it all seems fair when the argument for karate training is that of "empty hands" as opposed to the carrying of weapons to defend yourself.
Fair enough, but we are not living in decades past. Today's confrontations are more brutal and violent than ever before, and chances are, you are going to be hurt by whatever your attacker is using.
Why shouldn't you be able to defend yourself with any type of weapon, being this a broom stick, a comb, a fence paling, or better still, HIS own weapon? In our system of self defence, we are able to complement our martial studies with proper training in the use of many Okinawan weapons, and the traditions and Kata, mainly Matayoshi's and Ryu Kon Kai kobudo Kata, are maintained unchanged.
