Estimating the term…
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.
A pair of scissors comprising two blades for cutting a workpiece during their cutting strokes, comprising:
Apparatus for cutting a workpiece during a cutting stroke comprising two blades,
A method for manufacturing a scissor blade made from blade stock comprising a leading side determined by the blade cutting stroke direction and a face side comprising the operation of:
A method of manufacturing an improvement in at least one scissor blade in a pair of scissors, and said blade comprising a leading side (6) determined by the cutting stroke direction and a face side (8), both said sides forming a joint, and the method comprising the operation of:
