Often held but never touched, always wet but never rusts, often bites but seldom bit, to use me well you must have wit. What am I?

Why this works

This riddle cleverly plays with the various characteristics of a tongue. "Often held but never touched" refers to how we control our tongues without physically holding them, while "always wet but never rusts" highlights that our tongues are moist but, unlike metal, they don’t corrode. The phrase "often bites but seldom bit" implies that while our tongues can "bite" in terms of speaking hurtful words, they themselves don’t get bitten. Finally, "to use me well you must have wit" suggests that effective communication requires cleverness and intelligence, which ties everything back to the importance of our tongues in speech.
