Among the Red Hunters who are specifically descended from Inuit, their slaves
and animals are identified by an intricately knotted set of four leather strings,
similar to a collar. These are called bondage strings and, like the beaded collar,
the different types of knots used identify the specific owner.
Capture Collar
The capture collar consists of a loop of chain attached to two wooden handles in
such a way that it is easy to block off a slave's air supply as a measure of
physical control while maintaining a safe distance. It was described by the
author thusly:
"About my throat, closely looped, was a narrow golden chain. It was
controlled by two narrow wooden handles, in his hands... It was a girlcapture
chain... It is to be distinguished from the standard garrote, which
is armed with wire and can cut a throat easily. The standard garrote, of
course, is impractical for captures, for the victim, in even a reflexive
movement, might cut her own throat."
(John Norman, Savages of Gor, 1982)
Coffle Collar
A coffle is a line of prisoners, chained together. Therefore, a coffle collar is a
slave collar with a sturdy ring attached to it which allows a chain to be threaded
through the ring in order to control multiple slaves on the same chain. The chain
may be permanently attached or removable, depending on the number of slaves
in the coffle, and what they will be doing while chained in this fashion.
"The collars had front and back rings, were hinged on the right and locked
on the left. This is a familiar form of coffle collar. The lengths of chain
between the collars were about 3 to 4 feet long. Some were attached to the
collar rings by the links themselves, opened and then re-closed about the
rings, and some of them were fastened to the collar rings by snap rings.
Another common form of coffle collar has its hinge in the front and closes
behind the back of the neck, like the common slave collar. It has a single
collar ring, usually on the right, through which, usually, a single chain is
strung. Girls are spaced on such a chain, usually, by snap rings." (John
Norman, Savages of Gor, 1982)
