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 a primary bevel with ▪ the primary bevel extending from the cutting edge to the first surface, ▪ a first intersecting line connecting the primary bevel and the first surface and ▪ a first wedge angle θ 1 between an imaginary extension of the first surface and the primary bevel and o the second face comprises a secondary bevel with • the secondary bevel extending from the cutting edge, and • a second wedge angle θ 2 between the first surface and the secondary bevel, wherein the at least one cutting blade is mounted in the housing that • the clearance angle α between the skin contacting surface and the primary bevel or the secondary bevel 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 a primary bevel with ▪ the primary bevel extending from the cutting edge to the first surface, ▪ a first intersecting line connecting the primary bevel and the first surface and ▪ a first wedge angle θ 1 between an imaginary extension of the first surface and the primary bevel and o the second face comprises a secondary bevel with • the secondary bevel extending from the cutting edge, and • a second wedge angle θ 2 between the first surface and the secondary bevel, wherein the at least one cutting blade is mounted in the housing that o the first face comprises a first surface and a primary bevel with ▪ the primary bevel extending from the cutting edge to the first surface, ▪ a first intersecting line connecting the primary bevel and the first surface and ▪ a first wedge angle θ 1 between an imaginary extension of the first surface and the primary bevel and ▪ the primary bevel extending from the cutting edge to the first surface, ▪ a first intersecting line connecting the primary bevel and the first surface and ▪ a first wedge angle θ 1 between an imaginary extension of the first surface and the primary bevel and o the second face comprises a secondary bevel with • the secondary bevel extending from the cutting edge, and • a second wedge angle θ 2 between the first surface and the secondary bevel, wherein the at least one cutting blade is mounted in the housing that • the secondary bevel extending from the cutting edge, and • a second wedge angle θ 2 between the first surface and the secondary bevel, • the clearance angle α between the skin contacting surface and the primary bevel or the secondary bevel 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.
