Abstract: A knife including a first actuating part and a second actuating part of an actuating device, which forms a joint together with the first actuating part and can be pivoted in a first direction out of an unactuated position about a part pivot axis relative to the first actuating part in order to move a blade device that is movable relative to the first actuating part and the second actuating part and can be pivoted in a second direction in order to move the second actuating part into a blade-change position. An adjustment device is provided that has a control element by which the movement of the second actuating part in relation to at least one direction can be blocked.

Abstract: A utility knife has a housing in which a particle flow cross section is substantially constant or increases in a flow direction of particles from an inlet of the housing into an interior of the housing at an end of the housing to an outlet of the housing. A blade assembly has a blade with a cutting edge and is movable relative to the housing between a stowed position and an operating position for a cutting operation. A first actuating part and a second actuating part mounted movable relative to the first actuating part move of the blade assembly between the stowed and operating positions. First and second slotted links form a four-point linkage with the first and second actuating parts.

Abstract: A knife having an elongated housing having a channel-shaped laterally open recess and forming first and second housing surfaces, a blade, a support having a support outer surface and pivotal about an axis on the housing between an operating position and a blade-replacement position, and a cover having a cover outer surface and movable on the support between a position holding the blade against the support and a position free of the blade, the first and second housing surfaces tapering relative to each other in a clamping region or the outer surfaces tapering relative to each other in the clamping region. In the operating position the support is inside the housing and holds the blade inside the housing with only a part of a cutting edge of the blade exposed in the recess for engagement with material to be cut.

Abstract: A utility knife has a housing having a longitudinally open front end, a blade assembly including a blade and movable in the housing between a front end position and a rear end safety position, and a lever pivoted on the housing. Two links each have one end pivoted on the blade assembly and an opposite end pivotal on the lever so as to pivotally interconnect the blade assembly and the lever for relative movement of the blade assembly and the housing between the rear end safety position with the blade inside the housing and the front end position with the blade projecting longitudinally forward from the front end of the housing. A spring is connected to the links urges the blade assembly into the rear end safety position.

Abstract: A knife has two housing parts as well as a blade and a blade support. The support has a blade seat having a contact face normally engaging a blade face with the opposite blade face being freely accessible. The parts are movable between an operating position with the blade projecting and a stowed position with the blade wholly contained. A holder on the blade support secures the blade in the seat via interlocking formations that hold the blade against the contact face but that are so constructed that the blade has a degree of freedom in at least one direction in order to be detached from the blade seat. A latch on the holder has a bolt movable between a bolted position detachably fitted in the seat and holding the blade there and a released position out of the seat and allowing the blade to be replaced.

Abstract: A knife has a first part and a second part movably engaged to the first part along a path between an open position in which a housing interior is accessible and a closed position. A holding surface is fixed on and jointly slidable with the second part, and a third part is fixable on the first part, An actuator is movable on the second part between an actuated position and an unactuated position. An arm integral with or fixed on the third part is operatively engaged by the actuator and displaced on movement of the actuator between the unactuated position and the actuated position between a locking position securing the second part in one of the open and closed positions and a release position.

Abstract: A knife has a housing, a blade having a cutting edge and mounted on the housing with the edge extending transversely of a predetermined direction. An actuator is movable on the housing and pivots a blade guard on the housing about a guard axis for movement in the predetermined direction from a safety position in which the blade guard covers the cutting edge of the blade into a cutting position in which the blade guard is spaced from the cutting edge and the cutting edge is freely accessible and from the cutting position in a direction opposite the predetermined position into the safety position.

Abstract: The invention relates to a utility knife (10) comprising a housing that has a blade assembly (16), having a blade (23) having at least one cutting edge (35), the blade assembly (16) and/or a blade guard being movable relative to the housing between at least one stowed position and at least one operating position, the housing having at least one opening (22, 24). The special feature consists, inter alia, in that a particle flow cross section of the housing remains substantially constant or increases in the flow direction of the particles from an inlet (36) for the particles (34) into an interior (25) at a front end (18) of the housing to an outlet (37) for the particles (34).

Abstract: The invention relates to a blade assembly (40) comprising a blade support (14) and a blade (17) that can be detachably fastened in the blade support (14), the blade support (14) having a blade seat (16) having a contact face (42) for a first blade face (43), and a second blade face (44) opposite the first blade face (43) being substantially freely accessible, wherein the blade support (14) has a holder (20) for holding the blade (17) in the blade seat (16), comprising first interlocking formation associated with the blade support (14) and second interlocking formation associated with the blade (17) that interlockingly hold the blade (17) at least in a plane parallel to the contact face (42), the interlocking formation being designed such that the blade (17) has a degree of freedom in at least one direction (v1) in order to be detached from the blade seat (16).

Abstract: The invention relates to a utility knife comprising a first part (11) and comprising a second part (12) that is mounted so as to be movable relative to the first part (11), and comprising a blade assembly having a blade (16), and comprising an actuator having at least two links (17, 18) that hingedly interconnect the blade assembly and the first part (11) such that a mechanical linkage is formed that is movable by relative movement between the first part (11) and the second part (12), between at least one rear end position and at least one front end position, wherein the second part (12) is indirectly or directly movably connected to one of the links (18) or to the blade assembly in order to move the mechanical linkage.

Abstract: A utility knife has a housing, a blade, and a blade support carrying the blade and supported on the housing so as to be displaceable in a straight line with the blade between a safety position, a cutting position, and a blade-change position. A torsion spring biases the blade into the safety position.
