Kershaw Knives designs and manufactures a wide range of knives, including pocketknives, sporting knives, and kitchen cutlery. Kershaw is a brand of Kai USA Ltd., a member of the KAI Group. Kai USA Ltd. is headquartered in Tualatin, Oregon, United States.
Kershaw Knives was started in Portland, Oregon in 1974 when knife salesman Pete Kershaw left Gerber Legendary Blades to form his own cutlery company based on his own designs. Early manufacturing was primarily done in Japan. In 1977, Kershaw became a wholly owned subsidiary of the KAI Group. In 1997 the U.S. production facility was opened in Wilsonville, Oregon. Due to an expanding market, the facilities were moved to a larger production site in 2003. Currently, Kai USA manufacturing facilities are located in Tualatin, Oregon with some goods coming from their Japanese and Chinese factories.
Kai USA Ltd. has three lines of products; Kershaw Knives brand of sporting and pocketknives, Shun Cutlery, handcrafted Japanese kitchen cutlery, and Zero Tolerance, a line of premium and professional knives.
Kershaw has collaborated with a number of custom knife makers over the years. Collaborations include working with Hall of Fame Knife Maker, Ken Onion on Kershaw's SpeedSafe® knives, Ernest Emerson, Grant and Gavin Hawk, Frank Centofante, Rick Hinderer, RJ Martin, and more.
In 2002, Kershaw released a Steven Seagal model featuring stingray leather on the handle. In 2004 Kershaw developed a multi-tool for the National Geographic Society with National Geographic filmmaker Bryan Harvey. Kershaw has also released models in collaboration with Jeep, Orange County Choppers, the American Professional Rodeo Association, and the Rocky Mountain Elk Foundation.
Kai USA Ltd. and its Kershaw, Zero Tolerance, and Shun brands have a history of garnering industry awards. In May 2005, Kai USA Ltd. won four of the top awards at the Blade Show in Atlanta, Georgia. This was the first time in the show's history that one company won this number of awards in one year: 2005 Overall Knife of the Year, 2005 Most Innovative American Design, 2005 Kitchen Knife of the Year, and 2005 Knife Collaboration of the Year.
In June 2007, Kai USA won the Blade Show's "Overall Knife of the Year Award" with the Kershaw "Tyrade" (model 1850), in which the company's patent-pending Composite Blade technology using two different steels in the same blade was introduced. The blade steels were D2 tool steel at the cutting edge, and a spine of 154CM stainless steel.
2009 brought a Kershaw win for the Speedform (model 3500). In 2010, Kershaw won "American Made Knife of the Year" for the Tilt (model 4001) and Shun won "Kitchen Knife of the Year" for the Shun Premier line. Zero Tolerance's 0777 won "Overall Knife of the Year," the ZT-Rick Hinderer 0560/0561 won "Collaboration of the Year," and the Shun Fuji line won "Kitchen Knife of the Year" in the 2011 Blade Show.
Then in 2012, Kai USA Ltd. repeated its four-win sweep of the Blade Show awards. The Zero Tolerance 0888 won "Overall Knife of the Year", while the 0600 won for "Collaboration of the Year". The Kershaw Cryo won 2012's "Best Buy of the Year" and the Shun Taiyo was the 2012 "Kitchen Knife of the Year."
