A method of joining a razor blade to a blade support to form a razor blade assembly, the method comprising: a) selecting, for a laser scanning apparatus, values for one or more parameters comprising at least one of a spot size, a scanning speed profile, a pulse length, or a shield gas type and flow velocity, a pulse power, or a laser beam parameter product; b) operating the laser scanning apparatus in accordance with the one or more selected values to apply a laser beam to the razor blade; and c) generating an elongated weld area joining the razor blade and blade support to form the razor blade assembly, wherein the elongated weld area comprises a ratio of depth:width that is greater than about 2:1.

A razor blade (50) including a substrate (70) with a first portion (72) and a second portion (74). The first portion includes first and second generally parallel outer surfaces (72A, 72B). The second portion includes generally asymmetric first and second sections (76, 78) separated by a split line (SL₇₄). The first section (76) includes first and third facets (80, 84) and the second section (78) includes second and fourth facets (82, 86). The first and second facets (80, 82) are positioned between the first and second generally parallel outer surfaces and the third and fourth facets (84, 86). The split line (SL₇₄) passes through a tip (88) and is generally parallel with and extends between the first and second outer surfaces of the first portion. The second and fourth facets (82, 86) are located closer to the split line (SL₇₄) than the first and third facets (80, 84).

A shaving cartridge with a housing, having a primary guard at a front of the housing and a secondary cap at a rear of the housing. A bridge member having a primary cap surface and a secondary guard surface is positioned between the primary guard and the secondary cap. The bridge member has a plurality of spaced apart ribs extending transverse to the cutting edge of the first blade and defining a plurality of openings. A first blade has a cutting edge. The first blade is mounted to the housing between the primary guard and the primary cap surface. A second blade having a cutting edge extending in the same direction as the cutting edge of the first blade is mounted to the housing between the secondary guard surface and the secondary cap. A width of the bridge member is about 2.5mm to about 4mm.
