For Olfa Touch Blades. 

In 1956 Mr. Yoshio Okada, the founder of OLFA CORPORATION, invented the world's first Snap-Off Blade Cutter. The inspiration for this incredible idea came from breaking off segments of chocolate bars and analyzing the snap edges of broken glass.

Since then, OLFA® has been committed to making tools that improve how people cut materials by developing products that not only attain an inimitable level of sharpness but that are also practical to use from the user's standpoint.

To be used with Olfa Touch-Knives.
