As Ko-ken North America, we hold the official import and distribution rights for the region and work directly with Ko-ken Tool Co., Ltd. in Japan to bring authentic Japanese-made tools to the North American market.

Through our close relationship with Ko-ken Japan, we provide direct factory support, specialized product knowledge, and access to one of the most respected premium hand tool brands in the world. Known for exceptional precision, durability, and engineering, Ko-ken tools are trusted across the automotive, aerospace, medical, industrial, and manufacturing industries by professionals who demand uncompromising quality and performance.

Blackstone Global has helped establish Ko-ken as a leading premium tool brand throughout North America by combining world-class Japanese manufacturing with responsive local support, inventory, and distribution. In addition to Ko-ken’s extensive lineup of sockets, ratchets, and hand tools, we also provide custom tooling solutions tailored to specific customer applications and industries.

To better support the growing U.S. market, Blackstone Global recently expanded operations into a dedicated 5,000-square-foot U.S. warehouse facility stocked with thousands of parts. This investment allows faster fulfillment, improved inventory availability, and more efficient service for professional distributors, technicians, manufacturers, and enthusiasts throughout the United States.

Today, through our network of authorized distributors and direct customer relationships, Ko-ken USA continues to deliver premium Japanese tooling backed by exceptional service, technical expertise, and a true partnership with the manufacturer itself.
