The Ka-Bar 2221 Mark I Knife carries a legacy that dates back to World War II, when it was issued to the Department of the Navy for close-in fighting and utility work. The 5.13-inch clip point blade is epoxy powder-coated 1095 Cro-Van steel, giving it a non-reflective black finish that’s proven more durable than ever in modern testing. The classic oval Ka-Bar shape has been modernized with a Kraton G handle that resists sweat, chemicals, and water far better than the original materials. Tang-stamped USN, it ships with a MOLLE-compatible hard plastic sheath.
