Date Sep. 15, 1983.Method of making, from a strip, (for example metallic) a peg including a prismatic sheath from at least one surface of which extends a fin shaped so as to facilitate its downward penetration into the ground and increase its strength in the transverse direction, characterized in that the method comprises: shaping a strip adapted to form a plurality of pegs so as to define on each edge thereof a straight prismatic sleeve (1, 2) having all along its longitudinal dimension an opening (11, 21) extending along its edge which connects it with the intermediate strip portion (3) joining both sleeves to each other; and cutting said shaped strip both in a direction orthogonal to the generatrixes of said prismatic sleeves (1, 2) to form sections (A1, B1, A2, B2) the length of which is equal to the vertical dimension of the peg, and, in each said section, along a diagonal plane (A1, B1). The method can be used for making pegs for fences.
