Abstract

The invention relates to a wire stripper (1) having two stripper jaws (2, 3), two outer clamping jaws (19, 20), two inner cutting jaws (22, 23) and two grips (4, 5), the cutting jaws (22, 23) being displaceable from a base position into an end position during the closing of the grips (4, 5), the cutting jaws (22, 23) further having in each case a cutting element (24, 25) having a cutting edge (32, 33), the cutting element (24, 25) being arranged such that the cutting edge (32, 33) of the cutting element (24, 25) is in contact with the clamping jaw (19, 20) of the clamping jaw (19, 20) of the clamping jaw (19, 20) of the clamping jaw (19, 20) of the clamping jaw (19, 20). The cutting edges (32, 33) are positioned relative to one another at a defined distance (a) in a defined position in which the cutting jaws (22, 23) are moved towards one another, the distance (a) being adjustable by means of an adjusting screw (38) in a position, which is regarded as a base position. In order to further improve the wire stripper of this type, it is proposed that the adjusting screw (38) is connected to an adjusting wheel (45), which can be aligned with a marking (46) for the basic position, which marking is fastened to one of the plier jaws (2, 3).
