A determined thrust to the mid section.
Not seen until the last minute:
Parry the blade with a swipe while stepping in and off to the side.
Blade comes in from a right hand stab
Swipe away/parry with right arm as you step in and on angle to your left
This position puts you parallel ,or slightly behind the attacker which enable you to get away,strike and or deal with the truning to engage attacker.
If Blade is seen:
Parry with cross hand,strike weapon bearing limb with and or wrap weapon bearing limb and strike till attacker is down.
Blade comes right hand stab to mid section
left arm parries,swipes,pushes blade to outside,(My right)
I step into attacker,at angle to my left side
I use my right arm to strike attackers right forearm and or then wrap limb
I am parallel and or slightly behind attacker with available targets of neck,throat,face ,eyes ,nose
Hold arm secure and strike vital areas until opponent goes down
I also am at the side and can drive a downward kick into opponents kneee and drive it and him/her to the ground.
Never releasing the weapon bearing limb until attacker is desarmed or down and out allowing me to get away.
Here is a clip,from the static but it can be used with a thrust.
Part similar to my explanation at around 40 seconds (No limb control,just violence of action)
