Abstract
A knife has a pair of housing parts relatively shiftable between an open position and a closed position and a base on one of the housing parts forming a blade seat. A holding arm mounted on the base is movable relative thereto between a blade-holding position retaining a blade in the seat and a blade-change position freeing the blade so that in the blade-change position the blade can be switched. Interengaging formations on the other housing part and on the arm shift the holding arm from the blade-holding position into the blade-change position on movement of the housing parts from the closed position into the open position.
