The wall is my friend. Defending against knife attacks..

defending against knife attacks when standing against wall

1.attack: knife slash to face
defense: kimura lock

• hitch step to outside of uke
• parry w/ outside arm/hand
• inside arm /hand = punch face (hammer fist?)
• outside arm hand brings uke arm down w/ body
• inside arm wrap over uke elbow + hand grab other outside wrist
• use hip to create lock (elbow bends @ 90 degrees) + drive uke to wall
• back leg cross steps behind lead leg, keep using
momentum of hip to turn into direction away from wall
• project uke / take knife

2.
attack: forward knife stab
defense: tiger lock

• deflect knife / hitch step
• really go for a jodan zuki (uke has knife, btw!)
• trick for small people: twist wrist with pressure point
at forearm. get uke off balance
• after punch, immediately snake hand under uke elbow
• bend knees and up
• can grab obi knot
• turn both wrists, bring lat back. feels like a "boa constrictor"
• if does not work in a sec, change up to kotogaeshi

3.
attack: forward straight punch
defense: project uke with attacking arm

• parry
• step straight to side / parallel to uke / crossing ctr line
• get off balance like shihonage lock
• back leg steps forward and across own ctr line
• pivot hips / keep lock / arm stretched out
• kinda cut down w/ uke arm? projects uke forward

4. attack: forward straight punch
defense:catch arm and run

• hitch step
• made mistake, pin uke attacking arm between arm and ribs
• put hand on uke face and pin uke head to you
• finish taisabaki
• inside arm rides up uke center /
strike to chin / cause uke to back fall
• run

Other notes:
windmill shihonage against knife attacks: use softer arms / hands. no grabbing.
direct attacking arm into uke to avoid being cut by knife.
