Scissors or other two bladed cutting implements of the kind having a pair of pivotally connected blades, each blade having a cutting edge and a back edge forming respective opposite longitudinal edges of the blade. The improvement comprising forming the cutting edge of each blade so as to lie in the same plane as the back edge of the other blade in the closed condition of the scissors. Both the cutting edge and the back edge are formed at the junction of an inner broad surface of the blade and a respective longitudinal edge surface of the blade, and the back edge surface of one blade is coplanar with the cutting edge surface of the other in the closed condition of the scissors. The plane of those edge surfaces is at an angle other than 90 DEG relative to the plane of the broad inner surface of the blade. The invention also involves a method of forming the improved scissors in which the aforementioned edge surfaces are formed after the scissor blades have been connected and while those blades are in the closed condition.
