KA-BAR Mark I Knife Straight Edge blade. A remake of the ever-popular and sought-after knife issued to the Department of the Navy during WWII, the Mark I features a non-reflective black blade that is epoxy powder-coated. Tests prove the finish is more durable than ever. The classic oval shape of the original KA-BAR remains and has been modernized with a material nearly impervious to sweat, chemicals, water and wear - Kraton G®. Tang stamped USN. MOLLE compatible hard plastic sheath included.
