Abstract:
A cutting tool, particularly hedge shears comprising:a first elongated handle member; a second elongated handle member pivotally connected to the first handle member at a first pivot point; a first elongated blade member having a cutting edge extending substantially along its length and being pivotally connected to the first handle member at a second pivot point; a second elongated blade member having a cutting edge extending substantially along its length and being pivotally connected to the second handle member at a third pivot point, the first handle member and the first blade member being substantially symmetric to the second handle member and the second blade member, the first and second blade members being pivotally connected to each other at a fourth pivot point, the blade members being turnable relative to the fourth pivot point so that their cutting edges move in a scissor-like manner between an open and a closed position, the first, second, third and fourth pivot points forming a quadrangle in which an angle the vertex of which is formed by the first pivot point is at least about 160 degrees and approaching but not reaching 180Â° when the blade members are approaching their closed position, whereby the work done to close the shears creates a force which tends to close the blade members and is the bigger the closer the blades are to their closed position.
