The invention relates to a bolt cutter (1) which can be used for cutting a workpiece, especially a workpiece that is bolt-like. The bolt cutter comprises a fixed hand lever (3) and a movable hand lever (2). A cutting jaw (8) is fixedly connected to the fixed hand lever (3). The movable hand lever (2) via a ratchet gear (7) is coupled to a movable cutting jaw (6).

In an opening position of the cutting jaws (6, 8) the movable cutting jaw (6) lies against a rest (55) supported by a support spring (54). By manual application of an opening force, the movable cutting jaw (6) can be moved into an enlarged opening position from the mentioned opening position by pressurizing the support spring (54). When the manually applied opening force is removed, the movable cutting jaw (6) automatically returns to the opening position from the enlarged opening position due to the support spring (54).

Hand tools which have an ergonomic using a palm handle and finger handle designs which achieve mechanical efficiency and ease of use. The ergonomic handle is compatible with the muscle movements of an operator using a hand tool reducing muscle strain and pain. Optionally, the palm and finger handles can have ergonomically designed cushions. In an embodiment, the finger handle can have a finger set which has a forward finger flange, a tail finger flange and a pinky grip. The ergonomic handle can also use a relief washer system to achieve a smooth low frictional resistance cutting stroke.

A control device of a cutting tool for general use or gardening is revealed. The cutting tool, formed by a first component and a second component pivotally connected to each other, can be opened or closed gradually for cutting. The control device is pivotally connected to the second component. The control device can be pushed to act on the second component. The cutting tool performs multi-stage or one-time cutting according to the control device being pushed to the required position. Moreover, the first component and the second component are close to or away from each other under control of the control device.

The invention relates to an ergonomically designed tool for the intensive cutting of flowers and fruit, configured such that it can be gripped with the whole hand. According to the invention, the handles occupy a position in which they are perpendicular or almost perpendicular to the cutting blades, thereby minimizing the risk of injury to the upper limbs.
