Patent attributes
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.
