chink in one's armor

Hidden susceptible spot

A chink in one's armor is a weakness or vulnerability in someone otherwise well-defended.

The image is of a gap in plate armor where a blade might slip through.

The phrase applies to arguments, defenses, or personas: Her confidence seemed unshakeable, but his question found a chink in her armor.

Often shortened to chink in the armor.
