English Dictionary

slipjoint

noun

(chiefly attributive) A type of joint for a folding knife, involving a spring that helps hold the blade open against some pressure but does not lock it open in the sense of any positive engagement by the parts of any lock mechanism; it is thus a non-locking type of joint.

I always carry a slipjoint in my pocket for everyday tasks.
