Plural of Pliers
“Pliers” behaves like other two-part tool nouns: the lexical noun is plural, even when it names one physical tool. To count individual tools, count “pairs” rather than trying to create a singular “plier” for the ordinary tool meaning.
“Pliers” is a plural-only tool noun. One tool is normally “a pair of pliers,” and more than one tool is “two pairs of pliers.”
