  • Knife and support element therefor
    Patent number: 4178681
    Abstract: A knife, comprising a handle and an attached blade, is provided with an aperture in the handle for receiving a protrusion from a support element adapted to be attached to the knife. The support element comprises a sheath having an outstanding resilient tongue carrying the protrusion at a position such that, when the knife is inserted into the sheath, the protrusion resiliently snaps into the aperture in the knife handle to prevent withdrawal of the knife from the sheath until the protrusion is manually pressed out of the aperture by the finger of the user.
