Dremel with a cutoff disk.

A 4 or 5 inch angle grinder with a cutoff disc has much more power and
will work faster. The discs are also more robust, and less likely to
break and go flying in several directions (though the face shield is
still an excellent idea).

Dremel also makes a fiberglas cutoff disc. Somewhat more expensive than
the thin quarter-sized ones in the tube, but they last a LOT longer and
work a LOT better. I've never had one fly into pieces yet, though it
doesn't seem impossible.
