---Explorers of Gor, 5: 80-81
The Commonly used ko'lar " About my throat, snugly, there was a graceful, gleaming band of steel. Gathering my wits I simply reached behind my neck to release the catch, and remove it. My fingers fumbled. I could not find the release. I turned it slowly, carefully, because it fitted rather closely. I examined it in the mirror. There was no release, no catch. Only a small, heavy lock, and a place where a tiny key might fit. It had been locked on my throat! There was printing on the band, but I could not read it. It was not in a script I knew! Captive of Gor, page 7 " The small, heavy lock on a girls slave collar, incidentally, may be of several varieties, but almost all are cylinder locks, either of the pin or disk variety. In a girls collar lock there would be six pins or six disks, one each, it is said, for each letter of in the Gorean word for female slave, kajira; the male slave , or kajirus, seldom has a locked collar; normally a band of iron is simply hammered about his neck; often he works in chains, usually with other male slaves.
The Cord ko'lar " On some rence islands I have heard, incidentally, that the men have revolted, and enslaved their women. These are usually kept in cord collars, with small disks attached to them, indicating the names of their masters.
The hammered steel ko'lar " The girls were then motioned to the anvil. First Virginia and then Phyllis laid their heads and throats on the anvil, head turned to the side, their hands holding the anvil, and the smith, expertly, with his heavy hammer and a ringing of iron, curved the collar about their throats; a space of a quarter of an inch was left between the two ends of the collar; the ends matched perfectly; both Virginia and Phyllis stepped away from the anvil feeling the metal on their throats.
The message ko'lar "Did you note the collar she wore?" I asked. He had not seemed to show much interest in the high thick collar that the girl had had sewn about her neck. "Of course," he said."I myself," I said, "have never seen such a collar." "It is a message collar," said Kamchak. "Inside the leather sewn within, will be a message.
The ko'lar used in Torvaldsland " About her neck, riveted, was a collar of black iron, with a welded ring, to which a chain might be attached. " Marauders of Gor, page 85 " There were some one hundred bond-maids for sale in the shed. They all wore the collars of the north, with the projecting iron ring.
The Turian ko'lar " She wore bells locked on both wrists, and on both ankles, thick cuffs and anklets, each with a double line of bells, fastened by steel and key. She wore the Turian collar, rather than the common slave collar.The Turian collar lies loosely on the girl, a round ring; it fits so loosely that, when grasped in a man's fist, the girl can turn within it; the common Gorean collar, on the other hand, is a flat snugly fitting steel band. Both collars lock in the back behind the girl's neck. The Turian collar is more difficult to engrave, but it, like the flat collar, will bear some legend assuring that the girl, if found, will be promptly returned to her master. Bells had also been affixed to her collar.
The ko'lar of Red Savages "The red savages do not use steel collars. They use high, beaded collars, tied together in the front by a rawhide string. Subtle differences in the styles of collars, and in the knots with which they are fastened on the girls' necks, differentiate the tribes. Within a given tribe the beading, in its arrangements and colors, identifies the particular master. This is a common way, incidentally, for warriors to identify various articles which they own.
