Abstract
An appliance frame having a score line formed by pressing metal to form a plurality of dimples each having a substantially straight severed edge extending out of the plain of the metal and arranged in a substantially straight line to form the score line, thereby to weaken the metal sufficiently that it may be manually bent to form a substantially right-angle bend at the score line.
