A knife and sheath in combination in which a two-headed bolt supported in the knife handle may be positioned to interlock with the sheath. The bolt is symmetrical with respect to the knife to permit insertion of the knife into the sheath in either direction. The sheath has a portion of a resilient flexible wall positioned to engage one head of the bolt to urge the other into a hole in the other side of the sheath to secure the knife within the sheath until the bolt is pushed firmly in the opposite direction to disengage the knife and the sheath.
