SOG Specialty Knives & Tools Hard Nylon Sheath for Seal Pup & Seal Pup Elite SOG. Both models fit extremely tight due to their compact size. This sheath will hold both your knife and its environment very securely without fear of losing either during deployment or retention. You can hold the knife by the butt end or use the ball chain to wear it like a long distance lanyard. Since the sheaths are made from heavy duty nylon it will also hold up in wet environments with water mud or while immersed in water. It is also possible to carry the sheaths in the vertical or horizontal position inside a water borne raft or canoe. If using the sheath for a fixed blade knife consider the SOG Hard Sheath for the SOG Seal Pup or Seal Pup Elite inside that instead of the Velcro lining like the original sheaths. If using the SOG Hard Sheath for a Folding Knife the dimensions are the same but the spines are textured for visibility within the dark.
