In an evasive dagger disarming skill employment if the weapon holding hand has been seized and secured the following increases disarming chances and increases safety. Employing an opposing-forces grip of the weapon holding wrist joint and hand.
The first grip should be an over hand grip to reduce the likelihood of your enemy breaking your grip with an upward bicep curling action against your thumb joint. Your index finger and thumb of your overhand grip should be tightly fixed around the wrist joint with your remaining fingers tightly holding the weapon holding hand reducing your enemy’s capability to manipulate the blade against you.
Your secondary grip should be an underhand grip of the lower forearm immediately above your overhand grip of the weapon holding wrist and hand.
By pushing the seized and secured weapon holding hand away from you and levering it forward and diagonally groundward, you can interfere with your enemy’s balance making them direct some level of focus away from combative intentions and onto their stability. Lock your arms and use your torso, buttocks, and legs to redirect the weapon holding hand not arm on arm strength. Push your shoulder hard in against the enemy’s torso and slide your leg stamping boot into position boot to boot for a stamp kick threat neutralisation execution.
To hold a formidable enemy’s weapon holding hand with a single hand grip increases risk and to block forearm to forearm to forearm against a dagger holding hand is suicidal and shows a lack of practical smarts and knowledge regarding violence with an edged weapon. Only an armed fool would leave his weapon holding arm statically in mid-air against a blocking arm. Such training is more choreography and nothing like the reality of a skilled goal driven dagger armed enemy employing rapid multiple thrusts extending and retracting so fast that every thrust is a visual blur.
If the situation presents itself to redirect the weapon at your enemy, this would increase your safety by moving the dagger away from you and enhance your enemy disarming capabilities by causing them to drop their weapon to avoid being penetrated with their own weapon. If they are penetrated with their own weapon releasing the grip of their weapon will stop the penetration continuation and is a real self-preservation likelihood for a wounded desperate enemy.
The reality for military battlefield CQC is maximise and take advantage of every means of threat neutralisation.
