A shaving device for shaving a skin surface comprising • a housing with a skin contacting surface and • at least one cutting blade mounted in the housing, wherein the at least one cutting blade has an asymmetric cross-sectional shape with a first face, a second face opposed to the first face as well as a cutting edge at the intersection of the first face and the second face, wherein o the first face comprises a first surface and o the second face comprises a primary bevel having a straight or convex cross-sectional shape and a secondary bevel having a straight or concave cross-sectional shape with ▪ the primary bevel extending from the cutting edge to the secondary bevel, wherein a first intersecting line connects the straight or convex primary bevel with the straight or concave secondary bevel, ▪ a first wedge angle θ 1 between the first surface and the primary bevel or between the first surface and the tangent of the primary bevel through the cutting edge, ▪ a second wedge angle θ 2 between the first surface and the secondary bevel or between the first surface and the tangent of the secondary bevel through the first intersecting line, and wherein the at least one cutting blade is mounted in the housing that • the clearance angle α between the skin contacting surface and the clearance face which is the primary bevel or the first surface is ≤ 11°, • the effective cutting angle ε between the skin contacting surface and the bisecting line of the first wedge angle θ 1 is ≥ 10° and • θ 1 > θ 2. • a housing with a skin contacting surface and • at least one cutting blade mounted in the housing, wherein the at least one cutting blade has an asymmetric cross-sectional shape with a first face, a second face opposed to the first face as well as a cutting edge at the intersection of the first face and the second face, wherein o the first face comprises a first surface and o the second face comprises a primary bevel having a straight or convex cross-sectional shape and a secondary bevel having a straight or concave cross-sectional shape with ▪ the primary bevel extending from the cutting edge to the secondary bevel, wherein a first intersecting line connects the straight or convex primary bevel with the straight or concave secondary bevel, ▪ a first wedge angle θ 1 between the first surface and the primary bevel or between the first surface and the tangent of the primary bevel through the cutting edge, ▪ a second wedge angle θ 2 between the first surface and the secondary bevel or between the first surface and the tangent of the secondary bevel through the first intersecting line, and o the first face comprises a first surface and o the second face comprises a primary bevel having a straight or convex cross-sectional shape and a secondary bevel having a straight or concave cross-sectional shape with ▪ the primary bevel extending from the cutting edge to the secondary bevel, wherein a first intersecting line connects the straight or convex primary bevel with the straight or concave secondary bevel, ▪ a first wedge angle θ 1 between the first surface and the primary bevel or between the first surface and the tangent of the primary bevel through the cutting edge, ▪ a second wedge angle θ 2 between the first surface and the secondary bevel or between the first surface and the tangent of the secondary bevel through the first intersecting line, and ▪ the primary bevel extending from the cutting edge to the secondary bevel, wherein a first intersecting line connects the straight or convex primary bevel with the straight or concave secondary bevel, ▪ a first wedge angle θ 1 between the first surface and the primary bevel or between the first surface and the tangent of the primary bevel through the cutting edge, ▪ a second wedge angle θ 2 between the first surface and the secondary bevel or between the first surface and the tangent of the secondary bevel through the first intersecting line, and • the clearance angle α between the skin contacting surface and the clearance face which is the primary bevel or the first surface is ≤ 11°, • the effective cutting angle ε between the skin contacting surface and the bisecting line of the first wedge angle θ 1 is ≥ 10° and • θ 1 > θ 2.
