Abstract: A razor blade unit for safety razor has optimized shape and dimensions for body shaving, especially the regions of the axillae. The blade unit has an elongate blade with a rectilinear sharpened edge, and a skin contacting surface at which the length is 1 to 4 times the width and not greater than about 60 mm, e.g., 40 to 45 mm. The skin contacting surface has a footprint area of at least 450 mm2, e.g., 600 to 750 mm2, and a circularity which is not less than the lower of (i) 65%, and (ii) the circularity of a rectangle with the same length and width as the skin contacting surface and with corner radii of 30% of the width. In a plane perpendicular to the blade edge the skin contacting surface is convex and shaped to make at least a three point contact with an imaginary circumscribing circle with a radius of 15 to 70 mm, e.g., 25 mm. Guard cap surfaces in front of and behind the blade edge each have a skin contact area of at least 140 mm2,and their combined area is preferably at least 400 mm2, e.g.

Abstract: A safety shaving assembly for attachment to a razor handle has optimised shape and dimensions for body shaving, especially the regions of the underarm. The shaving assembly has an elongate blade with a linear sharpened edge, and a skin contacting surface whose length is 1 to 4 times the width, preferably 1 to 2.8 times the width, has a large footprint area of at least 450 mm2, preferably at least 600 mm2, and a circularity (as herein defined to relate the area enclosed by the perimeter to the length of the perimeter) of not less than 70%. The shaving assembly is substantially inflexible over a major longitudinal dimension in use. In preferred embodiments the circularity is about 80%. A preferred shape is an oval resembling a rectangle with semi-circular ends. The forward and rearward skin-engaging surfaces in front of and behind the blade edge each can have a skin contact area of at least 140 mm2, and their combined areas is preferably at least 400 mm2.

Abstract: A shaving system including a handle, a container and a plurality of blade cartridges accommodated in the container. The handle is selectively engageable and disengageable with said cartridges. A guide is provided to enable the handle to pass over a plurality of cartridges in a row in the container and to engage only the last cartridge in the row.

Abstract: A shaving unit includes a skin engagement surface member for contact with the skin in advance of a blade edge and defined by a series of resiliently mounted elements (9) defining between them slots (10) through which hairs can pass while being subjected to a light pulling force to increase the length of hair projecting from the skin prior to cutting. The skin engagement surface member may be a guard of the shaving unit or it can be mounted between two blades.
