Olfa
is a Japanese manufacturer of utility knives, founded in 1956 in Osaka, Japan. The name is derived from the Japanese words ''oru'' (折る, bend and break) and ''ha'' (刃, blade). ==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 ''GHQ'' (Supreme Commander of the Allied Powers) soldier in childhood had also broken off in sections.〔(Birth of OLFA cutter )〕 These snap-off blades and their associated handles are now made by many manufacturers in two standard sizes (9 and 18mm).
