A hand tool may include a head section defining a first grip portion, a handle section and a second grip portion. The head section includes a top jaw and a bottom jaw defining the first grip portion. The handle section includes a top handle and a bottom handle. The top jaw and the bottom handle forming a first unitary piece, and the bottom jaw and the top handle forming a second unitary piece. The first and second unitary pieces are joined at a pivot point. The second grip portion includes a top grip portion provided at the top handle and a bottom grip portion provided at the bottom handle. The top and bottom grip portions substantially face each other. The first grip portion is made of a metallic material and the second grip portion is made of a non-metallic material.

A pair of pliers include a handle unit, a head unit and at least one positioning unit. The handle unit includes two handles each having a mounting portion which is provided with a mounting slot and a regulating hole. The head unit includes two heads each provided with a working portion, a pivot hole and a plurality of positioning grooves. Each of the heads is pivotally mounted in the mounting slot by the pivot hole. Each of the positioning grooves is moved by rotation of each of the heads to align with the regulating hole. The at least one positioning unit is mounted in the regulating hole of one of the handles and locked in one of the positioning grooves of one of the heads.

The invention relates to a crimping pliers network (39) which comprises pressing pliers (2), an electronic control unit (31) (in particular a smartphone or a tablet) as well as a data storage device (37) (in particular a cloud storage (38)). According to the invention, a die (3, 4) of the pressing pliers (2) comprises an identifier (18, 19) which can be captured by a capturing device (21) of the pressing pliers. Data (48) from the data storage device (37) and being specific for the captured identifier (18, 19) is provided to the control unit (31). The data might be a desired pressing force curve (49), a desired pressing displacement curve (50) and/or information concerning a workpiece for which the dies (3, 4) are designated. In this way, it is possible to increase the process safety when using the crimping pliers (2). Furthermore, the invention relates to a method for pressing a workpiece.

Pliers for tightening parts for levelling cladding tiles, including: a first arm (1) with a handle (10) and a guide bar (11); a second arm (2) with a handle (20) and a contact surface (21) with a levelling wedge; a rotation shaft (4); and a supporting stop (3) comprising: a passage (31) for assembly in the guide bar; a shaft (32) assembled in a longitudinal slot (12) of the guide bar for the longitudinal movement of the supporting stop (3) with respect to the guide bar (11) and the relative rotation thereof between a fastening position with a pawl (13, 34) and a longitudinal movement position of the supporting stop (3) with respect to said guide bar (11); and a spring (33) which tends to maintain the supporting stop (3) in the fastening position with respect to the guide bar (11).

A combination tool assembly includes a pair of pliers. The pair of pliers is releasably attachable together thereby facilitating the pair of pliers to be closed around an object for gripping the object. The pair of pliers is detachable from each other and each of the pliers has a receiving element. A ratcheting driver is rotatably integrated into a respective one of the pliers and the engagement releasably engages a respective one of the pliers for pivotally attaching the pair of pliers together. A plurality of wrenches is provided and respective ones of the wrenches are removably attachable to the receiving element in a respective one of the pliers. In this way a user can accomplish a variety of jobs with a single tool thereby reducing the number of tools the user must carry.
