Abstract: A pipe cutting device includes a cutting element, a counter-holder, and a C-shaped working head. The counter-holder is formed by the working head and the cutting element protrudes into a C-opening. The working head merges into a foot part and the cutting element is accommodated in a displacement part. The displacement part is movably arranged with the cutting element in an offset part and/or the counter-holder has rollers, and each two rollers are mounted in pairs on a rocker part. A further pipe cutting device has an offset part and a counter-holder which are formed on a C-shaped working head, wherein the working head merges into a foot part which can also be used as a handle area, and the offset part can be offset relative to the foot part in order to change an opening width of the working head. In addition, the offset part has a cutting element.

Abstract: A knife has a knife handle and a blade, the blade being extendable and retractable in relation to the knife handle. A reinforcing part is provided which can support an extended portion of the blade, and is movable in respect of the knife handle and is detachably connected to the blade. Alternatively, the knife has a blade-moving carriage and/or a reinforcing part-moving carriage and a latching holder for latch-adjusting different extended positions of the blade is provided. In another embodiment, the blade-moving carriage has a holding magnet for holding cooperation with the blade. In yet another embodiment, a closing cap is arranged on the knife handle at the rear end of the blade, the closing cap closing the movement path for the blade-moving carriage and/or the reinforcement part-moving carriage.

Abstract: A hand tool has first and second tool legs that are connected in a pivot region and which overlap in an overlapping region both in an open state of the hand tool and in a closed state of the hand tool. The tool legs interact with a spring such that the tool legs can be pivoted, even beyond a basic open position, into an extended open position by the user in applying manual force against the force of the spring, the spring coming into action in the case of the additional pivot movement of the hand tool legs beyond the basic open position and/or in the case of a closing pivoting movement of the hand tool legs acts on different bearing surfaces of the hand tool legs.

Abstract: Plies have a first and a second plier limb which are rotatably held relative to one another on an axis of rotation an articulation region and form a jaw region on one side of the articulation region and handle sections on the other side of the articulation region. The jaw region has a cutting pattern with first and second cutting edges which, in the closed position of the pliers, are crossed with respect to a shear plane and which have a central plane running through the axis of rotation, perpendicularly to the shear plane in the closed position. The cutting edges are crossed to a greater degree in a region remote from the articulation, in the opening direction of the pliers, than in a region closer to the articulation.

Abstract: Pliers include a first and a second plier limb which are rotatably held relative to one another about an axis of rotation in an articulation region and which form handle regions on one side of the articulation region and a jaw of the pliers on the other side, the plier limbs being designed to cut a threaded bolt in an overlap region, using first and second cavities that can be superposed in alignment. A thread is formed in each first cavity in order to cut a threaded bolt. The thread is provided over only part of the height of the first cavity and over only part of the inner circumference of the first cavity.

Abstract: A pair of pliers has a first and a second plier leg, which are mounted so as to be rotatable relative to one another in a joint region and which form gripping regions on one side of the joint region and a plier jaw on the other side. A locking part fixes position of the pliers. The locking part is rotatably mounted on the first plier leg at a transition between the gripping region and the joint region of the plier leg, and, in the fixed position, fixes the pliers by contact with the joint region of the second plier leg. The locking part, in the fixed position and under load, is in supporting contact both with the joint region of the second plier leg and with the gripping region of the first plier leg in a plane perpendicular to the axis of rotation of the plier legs.

Abstract: A pliers-type cutting tool having two tool legs which cross at a joint pin and are pivotable about an axis of rotation in a pivot plane with respect to one another. The tool legs form gripping portions on one side of the joint pin and a pliers mouth on the other side. Cutting of the pliers mouth pass into a position one over the other, at least radially on the outside, for the first time in a closing region. The cutting edges have in the position one over the other only in the closing region a particular free length on this central plane, and that over the free length a greatest opening width is present along an intermediate length on the central plane, and that the greatest opening width makes up a third or more of the total length of the cutting edges.

Abstract: Pliers having two arms which cross at a pivot bolt, one of which being movable and the other being stationary, with grip sections being formed on one side of the pivot bolt, and interacting jaws being formed as the beak on the other side of the pivot bolt. The stationary arm further has a longitudinal slot with teeth, and the pivot bolt, which is located in a receptacle, is movable about the longitudinal axis thereof, counter to the force of a spring, out of engagement with the teeth into a release position and being held in the direction of the longitudinal axis with the aid of a blocking projection, which interacts with a blocking part in the receptacle. The blocking projection and the blocking part are designed to run over each other during assembly, overcoming the effect of the spring.

Abstract: A pipe cutting device with a positioning element and a counter-support, which are formed on a c-shaped working head, wherein the working head also transitions into a foot part that can also be used as a grip region, and the positioning element can be displaced relative to the foot part to change an opening width of the working head, wherein the positioning element can also be fixed on the foot part by a detent device, which has a hand-operable engagement element that interacts with a receiving part to fix the detent. In order to improve the design in terms of handling, the engagement element is situated on the positioning element and can be displaced together with the positioning element relative to the receiving part.

Abstract: Shears having two limbs connected at a revolute joint, each limb comprising a handle region at one end and a cutting edge at the other end. One limb is fixed relative to the revolute joint during an opening and closing movement, and one limb is movable. The limbs move between an open position and a closed position while being limited by a stop and, in the closed position, the cutting edges pass each other over substantially their entire length. On the handle side of the revolute joint, one limb extends relative to the other limb such that it is supported in a planar manner on both sides in a region of overlap with the other limb, wherein the limbs comprise surface regions which, in the closed position, rest against one another in the region in which they are on top of each other and are each exposed on the opposite side.

Abstract: Pliers have two pliers handles guided such that they cross one another in a joint region having a stationary joint bolt. Gripping regions are formed on the pliers handles on one side of the joint region, and working regions are formed on free ends of the pliers handles on the other side, said working regions extending to form a pliers jaw. The working regions have first and second toothed regions that come into contact when the pliers jaw is closed. In the first toothed region, in a sequence in the longitudinal extension of the pliers handle, the tooth tips end in a surrounding surface that is flat in the longitudinal section and in contact with same, and the tooth tips of the opposing second toothed region end in a surrounding surface that is convex in the longitudinal section and in contact with same.
