A sheath knife is a fixed bladed knife that fits in an either leather or material (nylon kevlar leather etc. ) sheath for protection of the knife and carrier.The blades vary in size shape and construction.In Australian law sheath knife has a different definition. In this case they are a kind of non-folding fixed-blade knife which has a sheath which withdraws into its handle thus giving something of the effect of an out-the-front switchblade.
