Abstract
Disclosed is a knife comprising a housing (11) with a blade fixture (12) which can be moved translationally in the longitudinal direction (x) of the housing within a receiving duct (A) of the housing (11). The blade fixture (12) accommodates the knife blade (13) between a first blade contact surface (38) and a second blade contact surface (31) in a closed position while an operator's attachment (14) is assigned to the base (G) and/or the blade locking mechanism (19) in order to translationally move the blade fixture (12). The operator's attachment (14) is retained on the base (G) outside the blade locking mechanism (19). Inner surfaces (35a, 35b) that border the blade fixture (12) and are located in the receiving duct (A) retain the locking mechanism (19) in the closed position in which the locking mechanism (19) rests against the base (G), or release the locking mechanism (19) in order to open the locking mechanism (19) and remove the blade when the locking mechanism (19) is moved forward and outward through the blade through-hole (37) into a blade replacement position.
