Rules to ponder:
1. If you can’t see you can’t fight: slash or poke their eyes and blind them. Most perps will not be expecting this.
2. If you can’t breath, you can’t fight: Slash the throat, punch to the solar plexus, break the nose so that blood goes down the throat.
3. If you can’t stand, you can’t fight: A hard kick to the side of the knees is quite effective in bringing some one down. Also tripping. Being suddenly dumped on your butt is psychologically alarming and may end the fight.
If you can’t think, you can’t fight: decapitate them.
