About Cold Steel and Lynn C. Thompson:

Cold Steel was founded in 1980 by Lynn C. Thompson with the mission of producing the strongest and sharpest knives in the world. Known for pushing the boundaries of knife design and performance, the company became famous for its American tanto blade style and overbuilt, combat-ready folders. Thompson, an avid martial artist and outdoorsman, infused Cold Steel's product line with a focus on real-world utility and tactical strength. He also became known for the company's high-impact demonstration videos, testing the strength and toughness of their knives in dramatic ways.

The Oyabun is one of Cold Steel's modern liner lock designs, developed with premium materials and safety features that reflect the company's emphasis on performance and durability.
