Well, IMHO a torque wrench is for precision tightening of fasteners so I restrict mine to that application. Most wrenches will run both directions because there are certainly left hand thread fasteners that need to be torqued.

I figure why risk messing the calibration up when I have plenty of ratchets and breaker bars that work perfectly for removing fasteners.

The situation you define, with a loctited fastener is the type where you could possibly apply more torque than the wrench is designed for inadvertently.
