A bow-type throwing tool includes a central body, a nocking string for an arrow, and elastic energy storage mechanism operated by the traction of the string. The elastic energy storage mechanism includes: two opposed primary levers connected with hinging to the central body, the nocking string being constrained by its opposite ends to opposite free ends of the primary levers; two opposed axial action thrust accumulators, defined on the central body; a loading element of the axial action thrust accumulators configured to induce a compression in the thrust accumulators following a traction of the nocking string.
