Seizing a Weapon or Object

Seizing a Weapon or Object is a rule found on page 12 (Armed Grappling) of GURPS Martial Arts: Technical Grappling, available in the free preview at http://www.warehouse23.com/media/SJG37-1644_preview.pdf
:Control Points applied to a weapon affect the weapon and
the limbs grasping it
This could be extrapolated when 2 people team up to grapple the same enemy, reflecting how grapplers might interfere with one another unless they find a way to cooperate.
For example, if 2 attackers grappled a target's torso, while that enemy would suffer the cumulative effects of the Control Points from both grapples, the attackers should also apply each's points against the other hands, with the arms suffering half as much.
Also:
:A weapon grabbed in two hands is treated as part of both hands
Extrapolating from this that the hands and object are treated as a collective object, the weight (or HP/ST) of someone could be considered collectively if either is hit with knockback.
Some sort of rule should probably exist in that case for knockbacks loosening grips.
