Well, from my experience Pivot refers to the look/rossi binders that pivot on a spring, can can rotate about 45 degrees in both directions. I know this because I have look and rossi (and look!) binders that say "pivot" on them. FKS, or turntable heals, refer to the fancy binders with the robot arms on them that spin 360 degrees. I know this becasue my FKS say "turntable" on the box that they came in. They also have robot arms and spin 360 degrees on a table like platform.
