pickaxe

Inherited from Middle English pykeaxe, pecaxe, pyke exe (“pickaxe”), an alteration (due to folk etymology association with pick and axe) of Middle English pikeyse, pikeys, pykois, from Anglo-Norman *pikeis, Old French picois, pecois, from Latin picōsa (“pickaxe”), from picca, ultimately from Proto-West Germanic *pīk (“sharp point, pike”). Doublet of pique and pike.
