Abstract: An elongated stock material for use in manufacturing shaving razor blades, the material including an elongated, flat strip of metal having a front edge and back edge extending along its length, a sharpened cutting edge portion extending along the front edge, a weakened portion between the front edge and the back edge, a blade portion between the cutting edge portion and the weakened portion, and a removable portion between the weakened portion and the back edge. Also disclosed are blades and cartridges made from the material, and methods and apparatus making and using the material.

Abstract: A process for manufacturing razor blades from a continuous strip of metal stock by stamping a plurality of openings in the strip for precise registry of the blade edge when employed in the razor and then running the stock through a device which partially slits the strip along lines which are precisely located with respect to the edges of the stock and the openings. The strip is then heat treated after which it is run through a device which splits the stock along the previously slit lines to form a plurality of continuous strands containing interconnected blades disposed end to end.

Abstract: A flat clip or staple is manufactured from a continuous strip of flat sheet material in coil form by first stamping out intermediate portions of material between each of the blanks to be formed into a discrete staple while retaining the blanks in the continuous strip. The strip is then subjected to a second stamping process where each discrete staple is severed from the strip, formed into the required shape and the excess waste material removed from the continuous strip. The second stamping process is located immediately adjacent the final stapling assembly operation, such that the staples never need to be transported to the final stapling operation site in separated form.

Abstract: A razor blade member has a first planar portion and a second planar portion connected to the first planar portion by a transition bend region. The longitudinal edge of the first planar portion remote from the transition region is sharpened to a cutting edge. The blade member also includes stress balancing deformation along the longitudinal length of the planar portions and adjacent the transition region. The bow of the second planar portion is less than 0.05 millimeter per centimeter length of blade member.

Abstract: A tool holder for retaining a cutting tool, the toolholder including a body portion, a clamp portion operably connected to the body portion, the body portion having a first jaw portion, the clamp portion having a second jaw portion, the jaw portions being adapted to receive the cutting tool therebetween, and a holding strap pivotally mounted on one of the jaw portions, the holding strap having a flat surface for engagement with a surface of the cutting tool.

Abstract: A chuck assembly includes a plurality of locking keys disposed within longitudinally extending grooves in an outside surface of an arbor and arranged to centrally locate and clamp a hollow work piece to a spindle.
