directing a laser beam having an adjustable power output at an upper surface of the razor blade; and
while advancing the laser beam along the razor blade:
a) applying the laser beam at a first power output to the razor blade over a first time period to form a keyhole in the upper surface of the razor blade;
b) reducing the first power output of the laser beam to a second power output; and
c) applying the laser beam at the second power output over a second time period after the first time period to the razor blade to form a weld area joining the razor blade to the blade support, wherein the second time period is longer than the first time period.
