Tinkering with Garrote
well, this is gonna be a little unorthodox approach to the topic but anyway ...
After a long training session, putting together some choreographies with "improvised weapons" for a pirate show, I ended up with a rope in my hands. The whole thing ends up with a "choke hold" using the rope as a Garrote, than a "throw" (a little bit perverted Uchi-Mata), still keeping a "choke hold", then pin (kneeling on thrown actors back) and the whole action is finished by "choking him to unconsciousnes". The poor-one with the rope around his neck has quite a lot to do to keep his hands on the rope and don't get hurt but after few hours of practicing, the final video record of the last attempt looks like it's doable.
ok, enough bragging now, and (finally) here comes the relation to GURPS.
With a Perk: Weapon Adaptation (Garrote to Judo, or Garrote to Wrestling):
Garroting rules remain the same as they are, plus possibility to perform Throws from Locks (MA118-119), garroting someone is considered to be a Choke Hold (or Head Lock) technique (grappling foe by a neck with both hands). Additional ST bonus from Wrestling to the "garroting contest" to determine DMG.
note: I didn't put this on SJ Forums and I will not
