Abstract: A shearing tool has a first unit with a first blade, rotatably coupled to a second unit with a second blade, at a first pivot having a first pin, so that displacement of the first blade relative to the first pin in a direction parallel with a first rotational axis is prevented, and the handle is connected to the second blade so that rotational movement of the handle relative to the second blade about a second rotational axis is allowed. The second rotational axis is defined by a second pivot interacting with the second blade and the handle at a distance from the first rotational axis in a direction away from a cutting edge contact point. When the shearing tool moves from an open to a closed position, the second blade is driven towards the first blade at the contact point for increasing the cutting capacity of the shearing tool.
