A hand operated shearing tool, comprising - a first unit comprising a first blade and optionally a first handle fixed to the first blade at a proximal end of the first blade, the first blade comprising a first cutting edge; and - a second unit comprising a second blade and a second handle connected to the second blade at a proximal end of the second blade, the second blade comprising a second cutting edge, wherein the second unit is connected rotatably to the first unit about a first rotational axis (R 1) defined by a first pivot, the first pivot comprising a first pin penetrating the first blade and the second blade; the first pin is connected to the first blade so that displacement of the first blade in relation to the first pin in a direction parallel with the first rotational axis (R 1) is prevented; the second unit is arranged to be rotated in relation to the first unit about the first rotational axis (R 1) between an open position of the shearing tool and a closed position of the shearing tool; and at least one of the first blade and the second blade is curved and the first blade and the second blade are biased against each other so that the first cutting edge and the second cutting edge are in constant contact at a cutting edge contact point when the hand operated shearing tool is moved between the open position and the closed position, characterized in that the second handle is connected to the second blade so that rotational movement of the second handle in relation to the second blade about a second rotational axis (R 2) is allowed; the second rotational axis (R 2) is defined by a second pivot interacting with the second blade and the second handle and being arranged at a distance from the first rotational axis (R 1) in a direction away from the cutting edge contact point; the first pin is arranged to penetrate the second handle through a through hole arranged in the second handle; the diameter of the through hole is greater than the diameter of the first pin for allowing movement of the second handle in relation to the second blade in a direction transversal to the first rotational axis (R 1); the through hole has a frusto-conical shape at the end of the through hole opening in the direction away from the second blade; the first pivot comprises a frusto-conical shape arranged coaxially with the first pin for interacting with the frusto-conical shape of the through hole; as a result, the second handle is arranged to exert a compressive force (F 2) to the second blade due to a shearing force (F 1) between the second handle and the second blade when the shearing tool is moved from the open position towards the closed position; and due to the compressive force (F 1), the second blade is driven towards the first blade at the cutting edge contact point for increasing the cutting capacity of the shearing tool. - a first unit comprising a first blade and optionally a first handle fixed to the first blade at a proximal end of the first blade, the first blade comprising a first cutting edge;
