Origin

late 16th century (originally denoting a harness-maker, then a slaughterer of horses): possibly from obsolete knack 'trinket' The word also had the sense 'old worn-out horse' (late 18th cent). It is unclear whether the verb represents a figurative use of 'slaughter', from the noun sense, or of 'castrate', from a slang sense of the noun, 'testicles'.
