摘要 A non-conductive substantially buoyant-in-water hand tool comprising an elongated handle portion formed of non-corrosive, non-conductive material having a density greater than water and an elongated working tool connected to and extending axially from a proximal end of said handle portion. The handle portion has one or more outwardly opening cavities formed into a side surface of the handle portion. An elongated tubular sheath formed of material buoyant in water covers and sealingly encloses and forms one or more airtight cavities whereby the effective density of the hand tool is less than that of water.
