To bend or curve something outward, especially the sides of an object; to create flanges.
Possibly from Old French flanche (to bend sideways), related to flank. Used in manufacturing and metalworking contexts.
In metalworking, flanching creates incredibly strong joints—by carefully flanching metal edges, blacksmiths could make armor that was both lighter and stronger than solid plates.
