    摘要: A safety razor blade unit has cap structure with upstanding fin elements directed perpendicular to the blade edges to define a cap surface featuring low frictional resistance characteristics during shaving. The fin elements are spaced at a pitch distance of 0.3 to 0.7 millimeter, are 0.3 to 1.0 millimeter in height and are substantially triangular in cross-section with an aspect ratio of 2:1 to 4:1.
