Abstract: An improved knife or bayonet scabbard of rigid material including a body and a clip. A swivel connection between the two allows limited rotation of the body with respect to the clip when the clip is extended for belt wearing. The body is restricted from rotation when the clip is realigned to an aligned position for inverted wearing as on the chest. The body includes an integral catch on one side of the blade receiving opening and an internal spring on the opposite side for biasing the blade of the knife toward the catch. An auxiliary flexible loop aids in holding the knife or bayonet in the scabbard.
