A sheath for a knife having a blade and a handle, the handle having a guard with a first and an opposing second portion. The sheath comprises a body with a cavity to receive the knife blade and a recess with one side forming a ramp to receive the first portion of the knife guard. The second portion of the knife guard is outside the sheath. A spring carried by the sheath engages the second portion of the guard and biases the guard so that the first portion of the guard is retained but not locked in the recess. To release the blade from the sheath, the thumb of the user presses against a lobe formed in the end of the spring to remove pressure on the second portion of the guard, allowing the first portion of the guard to be moved up the ramp side of the recess and out of the sheath, or, alternatively, the handle may be pulled with sufficient force to overcome the bias of the spring and draw the first portion of the guard up the ramp and thus the blade from the sheath. The sheath is secured to a belt with a " C" shaped pair of lips attached to the back of the sheath. An adaptor that locks into place behind one of the lips may be used for narrower belts.
