Originally founded in 1952 under the name Expert Cutlery, this growing manufacturer of scissors and shears initially employed five men who turned out approximately 600 pair of shears per week. About 28 different styles of shears were manufactured, produced by large grinding wheels with a gas-heated lead pot used for the heat-treating process.

The Expert Cutlery name was changed to Klein Cutlery in 1978. The company continued to grow and invest in state of the art equipment, such as CNC (computer numerical control) machine grinders and electronically controlled salt furnaces for heat-treating.
In August 2007, Klein Cutlery was acquired by and began operating under the name Klein Cutlery, LLC.  Klein Cutlery is an affiliate of Klein Tools, Inc., a leading manufacturer of hand tools and occupational equipment for professional tradesman. 

Klein Cutlery has not only manufactured the same high quality barber shears since 1952, but has grown to become the largest U.S. manufacturer of hot-forged scissors and shears for a wide variety of markets including textiles, sewing, poultry, electronics, fiber optics and pet grooming.

Located in the foothills of Allegany County in Bolivar, New York, Klein Cutlery now employs 60 people, manufacturing 4,500 pair of shears per day in its 18,000-square-foot facility. The product line has grown to over 500 different styles of scissors and shears, with distributors across the United States, Canada, Australia, and Europe.
