An additional utility of the collar, though it did not count as one of its four common purposes
An additional utility of the collar, though it did not count as one of its four common purposes, was that it made it easier to put the girl in various ties. For example, one can use it to tie her hands before her throat, or at the sides or back of her neck. One can use it with, say, rope or chain, to fasten girls together. One can tie her feet to her collar, and so on.
If the feet are tied to the collar the knot is always in the front, so that the pressure will be against the back of the girl’s neck and not the front. The purpose of such a tie is to hold the slave, not choke her. Gorean men are not clumsy in their binding of women.
