OLFA Art Knife Pro (AK-4)

The OLFA Art Knife Pro (AK-4) is a precision craft and hobby knife designed for fine cutting, modelling, and graphic arts. It features a signature yellow handle with an anti-slip elastomer grip and a textured metal chuck that holds interchangeable scalpel and saw blades.

OLFA was founded in Osaka, Japan, in 1956 by Yoshio Okada, who invented the world's first snap-off blade utility knife. The brand name OLFA is derived from the Japanese phrase 'oru ha', meaning 'to snap a blade'. The company continues to engineer and manufacture its cutting tools and high-grade blades in Japan.

OLFA Corporation remains an independent, privately held Japanese manufacturer headquartered in Osaka, distributing its precision cutting instruments globally across professional craft, art, and DIY sectors.
