Patent attributes
A knife has two housing parts as well as a blade and a blade support. The support has a blade seat having a contact face normally engaging a blade face with the opposite blade face being freely accessible. The parts are movable between an operating position with the blade projecting and a stowed position with the blade wholly contained. A holder on the blade support secures the blade in the seat via interlocking formations that hold the blade against the contact face but that are so constructed that the blade has a degree of freedom in at least one direction in order to be detached from the blade seat. A latch on the holder has a bolt movable between a bolted position detachably fitted in the seat and holding the blade there and a released position out of the seat and allowing the blade to be replaced.
