My 1968 air force survival knife wasn’t getting used because the sheath was falling apart. The brass studs holding it together were heavily corroded. This new sheath is a tight fit but should soften up after a coat of neetsfoot oul. The studs are black painted nickel and hopefully last a long time. I’m ok with the plastic reinforcement at the end of the sheath which my old sheath did not have. My old knife may not be Ontario (marked Camillus 1968) and therefore the strap is tight to fit around the handle, but it works.
