egy hajszál

• by a hair's breadth

• to a nicety

• to hang by a hair, to hang by a thread

• it was a close shave, it was a narrow shave, that was a close call, that was a near go

• to be a near go

• it was as near as dammit

• by a hair's breadth

• to escape by the skin of one's teeth

• within an inch of death

• by the skin of one's teeth, with the skin of one's teeth
