The body and the blade have correspondingly shaped apertures and lugs that co-operate together to hold the blade in place. A locking means further assists in ensuring that the blade remains locked to the body and includes a sliding klatch that engages an aperture in the blade and the body and is itself locked in place to thereby lock the blade to the body.
