If you have a Cressi Predator Knife (see SKU: CSBKB) and have lost or broken the sheath that came with the knife this is the perfect replacement/spare your looking for. Sheath is made from durable impact resistant plastic with rubber knife retainer loop for one-hand release and is corrosion resistant for years of reliable service. The sheath can be belt mounted or leg mounted with leg straps (see SKU: CSBSK). Sheath makes a great save-a-dive-kit item.
