 A shaving system with a blade member with a cutting edge of wedge shape that is defined by main facets with an included facet angle in the range of 10.degree.-17.degree. in the region forty micrometers from the cutting edge. The blade is mounted between leading and trailing skin-engaging surfaces so that the blade tangent angle is less than 20.degree. and the interior main facet of the blade is disposed at an angle of more than 150.degree. to a reference line that extends from the cutting edge of the blade to the skin-engaging point next forward of the blade edge.
