Unarmed defence against edged or blunt weapons should take into consideration the following :
An important thing to remember is to use your imagination both in your training and adapting the techniques to suit the situation.
When being attacked first look for anything that could be used as a weapon in your defence. If you were able to procure a weapon, use it to strike the weapon arm (on hand, wrist or elbow) of the attacker, then strike vital nerve points or other vulnerable targets on his body.
