Abstract: A pair of scissor blades illustrated in (FIG. 4); each blade comprising a cutting edge (3) arranged below a blade protuberance relative to the direction of the cutting stroke. The protuberance comprises a cutting edge grinding surface (4), a pressing ridge (5) and a blade side surface (6). The protuberance presses on skin creating sensitive reactions in the user prior to the rear located cutting edge damaging the skin. The cutting edge degree of sharpness is predetermined at the factory. A method of manufacturing the invention and for modifying standard prior art scissor blade shapes by grinding a cutting edge at a new angle of sharpness that inherently produces the safeguarding blade protuberance.
