I've got two "non contact voltage detectors". One from
Walmart, that takes button cells. Other from HF, takes two
AAA cells. Both seem to detect live wire. That kind of thing
might help trace the open, if it's in the hot side. Of
course, having both ends near each other, it's easy to use a
VOM to determine if the hot or cold is open. Or both.

A little pocket AM radio works well as a break finder. Tune
it so it
picks up the hum from a live line then run it up and down
the cord.
You may have to energize the wires separately to prevent
interference.
The AM radio will even pick up the RF harmonics from a tone
generator
like those used for tracing phone wires.
