What tool is used to remove broken bolts?

How do you remove a broken screw without an extractor?
Place a wide band rubber band flat in between the screw driver (we recommend bumping one size up from the screw head which caused the strip) and the screw, then apply hard, but slow force while turning the screw. If you’re fortunate, the rubber band will fill in the gaps caused by the strip and allow extraction.
How do you remove a broken bolt without a drill?
