==Snap-off blade== Founder Yoshio Okada and his younger brother Saburo worked for printing companies where they cut paper with razor blades, but the blades quickly became unusable as their edges wore out. The brothers invented blades with scored lines which could be snapped to reveal sharp unused sections of blade. This idea came to them when they recalled how a chocolate bar given to them by an American soldier in childhood had also broken off in sections.
