A garrote is a length of wire with wooden handles at both ends. The wire is placed across a victim's throat and crossed behind the neck; when the handles are pulled tight, the garrote strangles him
Locking garrotes are exotic melee weapons.
In order for you to use a garrote, your opponent must be helpless or unaware of you. You must make a grapple check (though you avoid the – 4 penalty for not having two hands free) to successfully begin garroting your opponent. Sneak attack damage does not apply to a garrote. Your garroted opponent must make a concentration check (DC 20 + your CMB + level of the spell he’s casting) to cast a spell with a verbal component, use a command word item, or use any magic requiring speech. You gain the following additional options when grappling with a garrote.
Choke: You cut off your target’s air supply so he has to hold his breath (see Suffocation, and the Swim skill for additional information). Any round you do not maintain the choke, your opponent can take a breath and restart when he has to begin making Constitution checks.
Locking: Once the initial grapple is successful, you no longer have to make additional rolls. In order to attempt to remove a locking garrote from a strangling person, a Disable Device (DC successful CMB value) check is needed to remove it, with a – 5 if the target attempts to remove it from them self.
