High Performance Tools of Convincing Quality.
Founded in 2012 by Jim Chase, Koken USA began sharing in the tool marketplace about an excellent product line of tools that was new to North America. He was so impressed by their quality and engineering that he claimed, "If we can just get them (Koken sockets) into the hands of the consumer, they will never buy anything else."
First with the introduction of Koken's broad line of standard sockets and tools, followed by their offering of custom sockets to meet specific customer requirements, Koken quickly developed a reputation for quality tools and outstanding customer service in North America.
