3.7.5. Gripping the striking surface of an opponents Weapon results in the disabling of that limb.
ok this says you cant grab the striking surface, and before you try to twist this back into a hey they rules dont say i cant kick you in the teeth argument, if you couldnt grab the nonstriking surface then the rule would be uttterly pointless as written and should instead read, Gripping an opponents Weapon results in the disabling of that limb.
Even playing Devils Advocate, I still personally believe that grabbing the chain should result in death. not an arm, death.
I beleve that any action that results in the direct destruction of weapons should be instant death.
