Oval frame razor

A safety razor blade unit comprising

• a plurality of elongate blades having longitudinally elongate sharpened edges and permanently mounted in spaced relation in a carrier, said carrier comprising a plastics material molding,
• a skin contacting surface surrounding the blade sharpened edges and including skin-engaging guard and cap surfaces, the skin-engaging guard surface being in front and the skin-engaging cap surface being at the rear of the blade unit, and the plurality of blades being located between the forward guard surface and the rearward cap surface and having the sharpened edges oriented in the same direction facing the guard such that during a shaving stroke the guard surface, the plurality of blade sharpened edges, and then the cap surface sequentially contact the skin,
• the aspect ratio of the length to width of the skin contacting surface being in the range of from 1:1 to 4:1,
• as seen in cross section in a plane perpendicular to the blade edges the skin contacting surface being convex,
• the overall length of the blade unit at the skin contacting surface being not greater than 60 mm,
• the skin contacting surface having a circumscribing perimeter confining a footprint area of at least 450 mm2, the guard surface having an area of at least 140 mm2 within the footprint area and being at least about 18.6% of said footprint area,
• and the circumscribing perimeter being so shaped that the footprint area confined by said perimeter has a circularity, wherein circularity (C) is a ratio between the area (A) of a shape enclosed by its perimeter (P) to the length of the perimeter as defined by the relation C=A/P2*4π*100, not less than the lower of
• (a) 65% and (b) the circularity of a substantially rectangular reference area RW having the same length and width as the footprint area of the skin contacting surface and having corner radii of 30% of said width.
