adze (n.) Look up adze at Dictionary.com
also adz, Middle English adese, adse, from Old English adesa "adze, hatchet," of unknown origin, perhaps somehow related to Old French aisse, Latin ascia "axe" (see ax). Spelling with -z- is from 18c. Adze "has been monosyllabic only since the seventeenth century. The word has no cognates, though it resembles the names of the adz and the hammer in many languages" [Liberman, 2008].
