Further the cutting member comprises a first bent portion (8), an intermediate portion (11), a second bent portion (9) and a base portion (10) that are made out of one single piece of material. The first bent portion being integral with the flat cutting portion. Said first bent portion is convex on the back side of the cutting member, and said second bent portion is concave on the back side of the cutting member. The proposed shape of the cutting member resembles an “S” shape or a question mark shape. ## Claims ### Claim at position 1 -15. (canceled) ### Claim 16 A cutting member for a shaving cartridge comprising: a front side; a back side opposite the front side; a flat cutting portion having a cutting-edge portion; a first bent portion, an intermediate portion, a second bent portion, and a base portion made out of one single piece of material; the first bent portion being positioned between the flat cutting portion and the intermediate portion, the cutting-edge portion being opposite to the first bent portion, and the first bent portion including the flat cutting portion; the second bent portion being positioned between the intermediate portion and the base portion and forming an angle of between 100° to 160° between the intermediate portion and the base portion; the first bent portion being convex on the back side of the cutting member, and the second bent portion being concave on the back side of the cutting member. ### Claim 17 (depends on 16) The cutting member according to claim 16, further comprising a platform portion having a front end that is made out of the same one single piece of material as the first bent portion, the intermediate portion, the second bent portion, and the base portion; the platform portion extends towards the first bent portion, and wherein the flat cutting portion is mounted on the platform portion. ### Claim 18 (depends on 17) The cutting member according to claim 17, wherein the platform portion has a length of between 0.2 mm and 1.5 mm from the front end to the first bent portion. ### Claim 19 (depends on 16) The cutting member according to claim 16, wherein the flat cutting portion is integral with the first bent portion and is made of the same one single piece of material at the first bent portion, the intermediate portion, the second bent portion, and the base portion; and wherein the flat cutting portion extends towards the first bent portion. ### Claim 20 (depends on 16) The cutting member according to claim 16, wherein the single piece of material has a thickness of between 0.07 mm and 0.18 mm. ### Claim 21 (depends on 16) The cutting member according to claim 16, wherein an angle of between 45° and 80° is formed between the flat cutting portion and the intermediate portion. ### Claim 22 (depends on 16) The cutting member according to claim 16, wherein the intermediate portion has a length of between 0.8 mm and 1.6 mm from the first bent portion to the second bent portion. ### Claim 23 (depends on 16) The cutting member according to claim 16, wherein the first bent portion includes a first radius of curvature of between 0.09 mm and 0.27 mm. ### Claim 24 (depends on 16) A shaving cartridge comprising the at least one cutting member of claim 16. ### Claim 25 A blade support comprising: a front side; a back side opposing the front side; a platform portion; a first bent portion; an intermediate portion; a second bent portion; and a base portion; wherein the platform portion extends towards the first bent portion; the intermediate portion extends between the first bent portion and the second bent portion, and an angle of between 100° to 160° is formed between the intermediate portion and the base portion; the base portion extends downward from the second bent portion; the first bent portion is convex on the back side; and the second bent portion is concave on the back side. ### Claim 26 (depends on 25) The blade support according to claim 25, wherein an angle of between 45° and 80° is formed between the platform portion and the intermediate portion. ### Claim 27 (depends on 25) The blade support according to claim 25, wherein the blade support has a thickness of between 0.07 mm and 0.18 mm. ### Claim 28 A process for manufacturing a cutting member for a shaving cartridge comprising: providing a flat piece of material; forming a flat cutting portion including a cutting-edge portion; forming a first bent portion, an intermediate portion, a second bent portion, and a base portion such that the first bent portion is formed between the flat cutting portion and the intermediate portion, and the second bent portion is formed between the intermediate portion and the base portion; and wherein the first bent portion is convex on a back side of the cutting member; and the second bent portion is concave on a back side of the cutting member; and the second bent portion forms an angle of between 100° and 160° between the intermediate portion and the base portion. ### Claim 29 (depends on 28) The process according to claim 28, further comprising the step of: forming a platform portion that extends towards the first bent portion, the platform portion being made out of a single piece of material with the first bent portion, the intermediate portion, the second bent portion and the base portion; and assembling the flat cutting portion on the platform portion such that the platform portion supports the flat cutting portion. ### Claim 30 (depends on 28) The process according to claim 28, wherein the step of forming the flat cutting portion includes forming the flat cutting portion out of a single piece of material with the first bent portion, the intermediate portion, the second bent portion, and the base portion; and forming the flat cutting portion integral with and extending towards the first bent portion. ### Claim 31 (depends on 28) The process according to claim 28, wherein the step of forming the first bent portion includes forming an angle of between 45° and 80° between the flat cutting portion and the intermediate portion.
