The SOG Spirit is a sleek and aerodynamic fixed blade knife that allows the user to unscrew the handle and use a broom handle (fits most common broom handles) to complete the spear! In a survival situation, use a branch to make the spear shaft and tighten it with a nail or the provided setscrew. With the provided handle the Spirit can be thrown or used as a cutting tool. The Spirit comes with a nylon sheath.
