It's an essential element, that since nowadays any brand had commercialized and it was used only the fisher's abilities. It's a practical tool, made in stainless steel, which allows releasing easily the rods that could have been blocked in cracks or in corals. It can also be used, thanks to its handhold, as an emergency releaser of blocked pieces in case of not having a hook. Made from a 3 mm thickness stainless steel foil, cut through laser and folded with the press. Rounded profiles to avoid damaging the hands. The hook nail's design facilitates the fixation on the heel of the rod in a very intuitive way, even blindly. It's considered to be a highly recommended element in terms of ecology because fishes don't visit the hollows where a harpoon has been screwed until a lot of time after its total disintegration. The Shaft Recover Tool is designed and manufactured in Italy by Cressi, an Italian brand pioneer in freediving, scuba diving and snorkeling equipment since 1946. The product is covered by a 2-year limited warranty.
