Abstract: The invention relates to a cutting device comprising a housing (14) and a blade carrier (15) to which a blade (16) is secured. Said blade carrier (15) can be moved by means of a lever element (26) of an actuation device at least between a secure position and a cutting position. In the secure position, said blade (16) is accommodated in the housing (14) so that it is inaccessible to the user and in the cutting position, it protrudes out from the housing (14) through a housing opening (32). The invention is characterized in that an extension (12) is arranged between a first handle (24) and the blade carrier (15).

Abstract: A cutting tool (1), and a method of exchanging an interchangeable blade as well as a cutting tool housing, in particular for severing flat and/or strand-form materials. The cutting tool (1) includes a housing (2), at least one interchangeable blade (8) arranged at a holding portion (6) of the housing (2), and a locking member (40) arranged movably on the housing (2) for locking the blade (8) to the housing (2). The housing (2) has first positively locking elements (23, 24, 26, 28) and the locking member (40) has second positively locking elements (42) which jointly lock the blade (8) in a given position to the housing (2).

Abstract: The invention relates to a knife comprising a housing (11) and an actuator (14) that can shift a blade holder (13) carrying a blade (47) in the housing (11) between at least one safety position and at least one cutting position, the blade holder (13) being tensioned by a spring (35). The characterizing feature consists in the fact that the spring (35) is attached to the housing (11) and to a first entrainment formation (25), and that a second entrainment formation (46) is associated with the blade holder (13), which second entrainment formation can be releasably engaged with the first entrainment formation (25) such that the first entrainment formation (25) can be moved by the second entrainment formation (46) from the safety position to the cutting position by movement of the blade holder.
