A primary cutting blade is mounted on the housing and has a cutting edge. A primary cap is located rearward of the cutting edge. A trimming element includes a trimming edge, the trimming edge and the cutting edge being opposite. A trimming guard bar includes a trimming guard bar edge. The trimming edge, the trimming guard bar edge, and a tangent to the trimming guard bar in the vicinity of the trimming guard bar edge define a theoretical limit trimming curve which is concave when viewed in relation to the trimming guard bar. The trimming guard bar is disposed behind and/or tangential to the theoretical limit trimming curve toward the second longitudinal side, such that the trimming guard bar does not project beyond the theoretical limit trimming curve. ## Claims ### Claim at position 1 -15. (canceled) ### Claim 16 A shaving blade cartridge comprising: a housing extending along a longitudinal axis having a top side and a bottom side opposite the top side, and first and second longitudinal sides each extending longitudinally along the longitudinal axis between the top and bottom sides; a primary cutting blade mounted on the housing between the first and second longitudinal sides, the primary cutting blade having a cutting edge; a primary cap, the primary cap being located rearward of the cutting edge; a trimming element mounted on the housing, the trimming element including a trimming edge, the trimming edge and the cutting edge being opposite; a trimming guard bar is provided on the housing, the trimming guard bar being forward of the trimming edge, the trimming guard bar including a trimming guard bar edge, wherein the trimming edge, the trimming guard bar edge, and a tangent to the trimming guard bar in the vicinity of the trimming guard bar edge define a theoretical limit trimming curve which is concave when viewed in relation to the trimming guard bar, and wherein the trimming guard bar is disposed behind the theoretical limit trimming curve toward the second longitudinal side and/or is disposed tangential to the theoretical limit trimming curve toward the second longitudinal side, such that the trimming guard bar does not project beyond the theoretical limit trimming curve in a direction opposite of the direction of the second longitudinal side. ### Claim 17 (depends on 16) The shaving blade cartridge according to claims 16, wherein the primary cap is behind the theoretical limit trimming curve toward the second longitudinal side. ### Claim 18 (depends on 16) The shaving blade cartridge according to claim 16, wherein the theoretical limit trimming curve is tangential to the guard bar in the vicinity of the trimming guard bar edge along a distance from the trimming guard bar edge between 5% and 20% of an orthogonally projected length of the trimming guard bar. ### Claim 19 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming guard bar is provided with a curved external surface, the curved external surface being destined to face the skin of the user, wherein the curved external surface has a curvature which is between about 3 millimeters and about 8 millimeters. ### Claim 20 (depends on 19) The shaving blade cartridge according to claim 19, wherein the curved external surface has a curvature which is between about 6 millimeters and about 8 millimeters. ### Claim 21 (depends on 16) The shaving blade cartridge according to claim 16, wherein the theoretical limit trimming curve is a portion of a circle or an ellipse. ### Claim 22 (depends on 21) The shaving blade cartridge according to claim 21, wherein the curvature of the theoretical limit trimming curve is between about 6 millimeters and about 8 millimeters. ### Claim 23 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming element includes a trimming blade support and a trimming blade, the trimming blade including the trimming edge, and the trimming blade being supported by the trimming blade support. ### Claim 24 (depends on 16) The shaving blade cartridge according to claim 16, further comprising two retainers retaining the blades on the housing. ### Claim 25 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming guard bar includes fins. ### Claim 26 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming guard bar includes a smooth surface. ### Claim 27 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming guard bar is curved and has a radius between about 7.3 and about 7.8 millimeters, wherein the theoretical limit trimming curve is a portion of a theoretical circle, wherein a center of the theoretical circle is positioned between about 7.3 and about 7.7 millimeters along a transversal axis toward the second longitudinal side from the trimming guard bar edge and between about 0.8 and about 1.2 millimeters along a lateral axis toward the top side from the trimming guard bar edge. ### Claim 28 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming guard bar is curved and has a radius of about 7 millimeters, wherein the theoretical limit trimming curve is a portion of a theoretical circle, wherein a center of the theoretical circle is positioned between about 6.5 and about 7 millimeters along a transversal axis toward the second longitudinal side from the trimming guard bar edge and between about 1.5 and about 2 millimeters along a lateral axis toward the top side from the trimming guard bar edge. ### Claim 29 (depends on 16) The shaving blade cartridge according to claim 16, wherein the trimming element is sandwiched between the housing and the primary cap. ### Claim 30 (depends on 16) A shaver comprising a handle and a shaving blade cartridge according to claim 16, the shaving blade cartridge being connected to the handle.
