1. knife vs empty hand._ knife thrusts midsection, met by crossblock or parry. collapse elbow on top of defense - you kind of pivot around 180 degrees so your shoulder/back is leaning against defender (almost like your falling on him), you can then thrust over the shoulder and or sipa with right leg or if defender gives space go thrust to slash as you pivot back around.
2. knife vs knife - takedown, very similar to Ray's palisut entry to takedown, takedown in such a way so the guys feet or foot goes stright up which is captured by the blade. (Again, Ray did the same exact one with the kerambit)
3. knife vs knife - dumog to disarm._ palisut with knife (reverse grip) to capture opponents knife with you live hand._ Cut/dumog to inside elbow bringing the kneck down into a slash to the neck._ Live hand, which still controls wrist lock goes to partners right ear as you blade hooks around other side - clamp neck with knife and forarm ._ Disarm and cut out (keep your forarm checked on neck)- pivot from elbow to thrust to midsection.
4 empty hand vs knife - like knife tapping - partners knife comes in on a 1 line - picked up with right palisut as left direct hits. As knife is_ passed downward left hand checks knife as right hand hits. Armbar to sipa or "planting the rice"
