Abstract: A pair of scissors has two shears movably mounted to pivot about an axis, each of the shears having a blade (3) extended by a shank (4, 5). The first shank (4) is covered by a grip in the form of an elongate body that is provided with a lateral opening (8) and that is suitable for being inserted transversely between two fingers of a hand to a position where it bears against the crook where the two fingers meet. The second shank (5) is terminated by a half-ring forming a cradle (10) for receiving the thumb. The first shank (4) is a bent shank. The lateral opening (8) in the elastically deformable grip extends into the inside of the grip forming a sheath into which the first shank (4) can be inserted in adjustable manner by slidable movement. The end of the cradle (10) that is closer to the first shank (4) is bent towards the inside of the cradle to form an abutment (11) for retaining the thumb.
