Abstract
A method is provided which produces a head of piolet, all in one piece, by punching out a metallic blank (i.e. a long cross-shaped blank whose outline is symmetrical with regard to its longitudinal axis and comprises four parts: a peen part, a pike part, and two lateral fastening flaps) from a plate of metal, and then by the folding of that metallic blank symmetrically with regard to its medial plane, along its longitudinal axis or on both sides thereof, at least along that portion of length which corresponds to the pike. The blank is eventually shaped approximately along an arc of circle which is located along the medial plane of the blank before mounting upon the handle of the piolet.
