WEAPON DEFENSES
In jiu jitsu you learn defenses against various weapons.  The ones here are what I have learnt so far.
COSH (thats a stick) ATTACKS
BOTTLE ATTACKS
KNIFE ATTACKS
CHAIN ATTACKS
Downward strike- ippon seio nage
Backhand strike- ko soto waza
Downward strike- arm lock 1, pull off
Backhand strike- swing round
Stab to the stomach- wrist lock 1
Stab to the groin- wrist lock 2
Stab to the face- wrist lock 4
Slash to the face
Stab to the kidneys- arm lock 6
Backhand attack- whack it down and take to floor

Don't throw bottle attacks- it's naughty.
