Abstract
A shaving blade cartridge includes a housing having first and second longitudinal sides extending between top and bottom sides. 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.
