Abstract:
1. A knife comprising: a housing having a front end; an operating part movable on the housing between an advanced position and a retracted position; a blade holder connected to the operating part, carrying a blade, and movable relative to the operating part in the advanced position thereof between a first cutting position with the blade projecting from the front end, a second cutting position offset from the first cutting position and with the blade also projecting from the front end, and a safety position with the blade recessed in the housing rearward of the front end, whereby a cutting force applied to the blade in the first cutting position moves the blade into the second cutting position; spring means for biasing the holder into the safety position; and a brace element movable between an engaged position braced between the blade holder and the housing in the first cutting position and a disengaged position out of engagement with the blade holder or the housing in the second cutting position such that movement of the blade holder into the second cutting position in the advanced position of the operating part moves the brace element into the disengaged position so the blade holder can move into the safety position without movement of the operating part from the advanced position and such that in the engaged position the brace element holds the blade in the first cutting position but in the second cutting position the brace element is disengaged and the spring means can return the blade holder to the safety position while the operating element remains in the advanced position; and an actuating link engaged between the operating part and the blade holder.
