A novel method of making an easy-open can end closure for insuring better control over the integrity of the closure, especially in tougher sheet metal such as steel, comprises the steps, after forming and longitudinally scoring-to-fracture the closure, of (a) providing a swageable strip of the metal extending along an edge of the line of fracture and overlying that edge, and (b) then swaging and dilating that strip radially into more intimate overlapping relation to the line of fracture to cause it to tightly close.
