What does clencher mean?
A clencher is, most literally, someone or something that clenches — that grips, grasps, or holds firmly, whether it is a person tightening their fist, jaws, or grip, or a tool or mechanism designed to fasten by pinching or pressing together. By extension, the word has also come to describe a figurative kind of grip: a statement, piece of evidence, or argument so persuasive that it effectively closes the discussion, settling a matter beyond dispute. In this sense a clencher is the point on which a decision turns. The word derives from the verb clench, itself a long-standing variant of clinch, and in contemporary English the closely related noun clincher is markedly more common, covering much of the same ground. Clencher survives chiefly in informal speech and writing, where its physical overtones — tension, force, finality — lend it vividness. It is a compact, expressive word for anything that holds tight or seals the deal.
A person or thing that clenches, grips, or fastens tightly.
"He was a jaw-clencher during tense negotiations, grinding his teeth without realizing it."
Often used in compounds describing habitual tension, such as tooth-clencher or fist-clencher.
A fact, argument, or remark that decisively settles a question or wins an argument.
"The photograph turned out to be the clencher in the investigation."
This figurative sense overlaps heavily with the more common word clincher.
The plural follows the standard -s pattern and applies equally to people or things that clench and to arguments or points that settle matters.
"Every debater needs a few good clenchers ready for the closing minute."
'Clencher' does double duty — it can be a fist, a nail, or the killer fact that ends an argument.

Etymology of clencher
Clencher is formed from the verb clench by addition of the agentive suffix -er, following the standard English pattern for nouns denoting a person or thing that performs an action. The verb clench is an old word, attested in early Middle English and descended from Old English clencan, meaning to hold fast or grasp. Clench has long existed alongside its variant clinch, and the two spellings gave rise to parallel nouns — clencher and clincher — of which clincher has become the dominant form in modern English.
