As fotch hinted at, there are two types of plastic reels made by several manufacturers:
-) Paterson style: true ratched system with balls serving as automated wedges
-) Jobo style: a simple, two reels system with your thumbs holding and releasing the film edges (foolproof with 35mm)

I use it in few situations only
You don't want it on the emulsion.
