1. Tongs, formed from a material having inherent flexibility, comprising: an arms section comprising a pair of similar-length arms each having an inner face and an outer face, an integral junction portion, each arm merging at one, thereby inner end thereof with the integral junction portion for flexing to bring the respective, thereby-defined inner faces of the arms into contact at free, opposite-end portions of the arms, and a retaining shoulder projecting from the inner face of each arm at the merger of the arm and the junction portion; and a fulcrum block nestable within the junction portion for bearing against the junction portion and retaining shoulders, whereby, when the free, opposite-end portions of the arms are urged together to grip an object, to cantilever the arms from the retaining shoulders bearing against the fulcrum block.
