摘要： 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. In preferred embodiments of the invention the length is not greater than 60 mm.

摘要： 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 60 mm, preferably 40 to 45 mm. The skin contacting surface has a footprint area of at least 450 mm2, preferably 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 three point contact with an imaginary circumscribing circle with a radius of 15 to 70 mm, preferably 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. 450 to 500 mm2. A preferred shape is rectangular with semi-circular ends.
