Ka-Bar

Ka-Bar (trademarked as KA-BAR, capitalized) is the contemporary popular name for the combat knife first adopted by the United States Marine Corps in November 1942 as the 1219C2 combat knife (later designated the USMC Mark 2 combat knife or Knife, Fighting Utility), and subsequently adopted by the United States Navy as the U.S. Navy utility knife, Mark 2.

The Kabar was standard issue for US Marines when they returned to Hawaii in 1943. US Marine Les Dillon preferred the knife over his own bayonet.
