KA-BAR Big Brother Knife Straight Edge blade with serrated back. Designed in cooperation with the highly-trained folks at S.E.I.G.E. (Strategic Edge Impact Global Enterprise) of Webster, NY, the high-carbon, non-reflective black blade of the Big Brother is epoxy powder-coated and 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®. Featuring a serrated top and straight bottom, the "Big Brother" is a perfect addition to the Kraton G® line. Tang stamped USA. Leather sheath included.
