Synonyms Pare, Peel, Shave off. To pare would be to remove the area only with a knife or comparable instrument; to peel is to pull off your skin or rind. “That is peeled that is deprived of a normal level or integument spread over it.” (C. J. Smith, Synonyms Discriminated, p. 603.) The figurative uses of those two words tend to be limited. Shave or shave down still appears figurative you should definitely implying the usage a razor, and it is controlled in its definition by that original feeling; thus it is usually limited by dressing off the area.
