  • Pointed weapon with a springing device
    Patent number: 5722169
    Abstract: The dagger described has a spring device. A pointed blade (24) is mounted so that it can move in a housing (20) from a retracted position to a projecting position. A spring (30) is fitted between the housing (20) and the blade (24) to bias the blade (24) towards the projecting position. A releasable catch (26) fitted to the housing (20) engages in a recess (28) in the blade (24) when the blade (24) is in the retracted position and secures the blade so that it cannot be forced back into the housing (20) when the blade (24) is in the projecting position. The catch (26) has a release element (44) made of flexible, high-tensile strength material in the form of a loop (46) in which a finger can be inserted. The housing (20) has a baseplate (40) and attachment straps by means of which the dagger can be secured to the user's forearm (41).
