Pvt. Young captured a photograph on November 29, 1918, showing Henry Disston and Sons in Philadelphia, PA. The image depicts SUINGER grinding machines being used to sharpen crosscut saws. The machines ensure that each saw is ground to a tapering thickness, making the cutting edge uniform and providing clearance for the blade's body when in use. The photograph was cleared by the censor on December 2, 1918.
