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. Please note, due to state regulations KA-BAR cannot ship the big brother knives to CA or MA.
