Abstract
A scissors has first and second arms with each arm having a finger receiving portion at one end. There is a removable metal blade having an outer edge and an inner cutting edge for each arm. A flange on each arm abuts the outer edge of the respective blade. A pair of inward projections on each flange each has a forwardly extending nose portion and a sloping rear portion and is engaged in a complementary opening in the adjacent blade. A finger extending inwardly from the forward end of each flange overlies a portion of the adjacent blade and is adapted to be engaged by the blade of the other arm when the scissors is in the closed position. A pivot structure passes through the arms and blades securing them together.
