Kai USA, Ltd., founded as Kershaw Knives in 1974, began with one mission: to design and manufacture tools that knife users would be proud to own, carry, and use. Today, premium materials, state-of-the-art manufacturing, extremely tight tolerances, and meticulous craftsmanship ensure that each Kershaw knife or tool provides a lifetime of performance and pride of ownership. The Kershaw brand is especially known for innovative technologies and materials, resulting in numerous industry awards. We manufacture most of our products in our 55,000 sq. ft. facility located south of Portland Oregon, in the city of Tualatin. Our campus houses a state-of-the-art manufacturing facility, our design, engineering, and manufacturing teams, as well as the customer service experts who sell and support our Kershaw brand knives and tools.
