ABSTRACT:
A pair of scissors has two elements that are cross-wise rotationally movably assembled in a hinge, each of said elements consisting of a blade and an arm. The arms each terminate in a ring for a user's finger. The general direction of the blades and the arms in a closed position of the scissors is making an angle large enough to place both rings on the same side of an extension line of the general direction of the blades. The blades are curved and have different lengths and heights, the upper blade being the shorter and higher and optionally provided with a protruding nose part, and the lower blade is relatively narrow and provided with a bulb shaped tip and a chamfered and/or rounded inner edge said distal end of said back edge of said upper blade has a nose part protruding a distance (n1) from the distal end of the cutting edge of the upper blade and having a distance (n2) from the cutting edge of the lower blade in a closed position of the scissors.
