Olfa Corporation (オルファ株式会社 Orufa Kabushiki-gaisha) 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). The company is known for inventing the snap-off blade and the rotary cutter.
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.
These snap-off blades and their associated handles are now made by many manufacturers in two standard sizes (9 and 18mm).
Their products include heavy-duty and specialty cutting tools for the building industry, safety tools for industrial applications, rotary cutters, self-healing mats, art knives and rulers for the crafting industry.
