A scissors (10) includes a first blade member (14) and a second blade member (16) which is pivotally coupled to the first blade member about a pivot joint (12, 32, 46, 50), wherein the blade members include first (18) and second (22) cutting edges, respectively, that are in contact with one another. The pivot joint is coupled to the second blade member to incline the second blade member relative to the first blade member so that the inclination of the second blade member produces a transverse pivot axial load at the pivot joint to produce tension and friction along the cutting edges. Further, the first and second blade members include first and second ride areas, respectively, which are spaced from and free of contact with one another due to the pivot joint so that the scissors are substantially free of any friction or drag at the ride area.
Une paire de ciseaux (10) comporte un premier élément de lame (14) et un second élément de lame (16) couplé en pivotement avec le premier élément de lame par une articulation à pivot (12, 32, 46, 50). Les éléments de lames comportent un premier (18) et un second (22) bords coupants respectifs, en contact mutuel. L'articulation à pivot est couplée au second élément de lame de manière à l'incliner par rapport au premier élément de lame, pour que l'inclinaison du second élément de lame produise une charge axiale, transversale par rapport au pivot, ce qui produit une tension et une friction le long des bords de coupe. En outre, les premier et second éléments de lame comportent une première et une seconde zones de chevauchement qui sont espacées et sans contact mutuel grâce à l'articulation à pivot, si bien que les ciseaux sont sensiblement sans friction ou sans force de traînée dans la zone de chevauchement des branches.
