The story of Case XX isn’t merely about one factory; it’s about a sprawling dynasty of American cutlery. To truly understand the blade in your pocket, you must look back to the "Little Valley" era of New York and the companies that share the exact same DNA.

The Foundation: Cattaraugus Cutlery

The entire Case legacy begins at the Cattaraugus Cutlery Company in Little Valley, New York. The four brothers—William Russell (W.R.), Jean, John, and Andrew Case—all learned the cutlery trade there while working under their brother-in-law, J.B.F. Champlin. Cattaraugus was the industry powerhouse of the late 19th century. Without the hands-on manufacturing and wholesale training the brothers received in those halls, the Case name as we know it might never have existed.

The Founding of Case Brothers (1896)

Armed with the knowledge gained at Cattaraugus, three of the brothers—Jean, John, and Andrew Case—struck out on their own. In 1896, they officially founded the Case Brothers Cutlery Company in Little Valley. It is a common historical misconception that William Russell (W.R.) Case was involved in this venture; however, he had absolutely nothing to do with the original Case Brothers firm. Jean, John, and Andrew built the company from the ground up, famously selling their premium handmade knives from the back of a wagon.

The Rise of W.R. Case & Sons (1902–1905)

While Jean, John, and Andrew established the Case Brothers name, the brand we recognise today as W.R. Case & Sons was actually the brainchild of the next generation. In 1902, J. Russell "Russ" Case (the son of W.R. Case) broke away to form his own jobbing business, W.R. Case & Son.

The pivotal shift occurred in 1905. The company officially evolved into W.R. Case & Sons when H.N. Platts—who had married Russ’s sister, Debbie Case—joined the firm. This strategic partnership between Russ Case and H.N. Platts provided the capital and momentum needed to move operations to Bradford, Pennsylvania, allowing the company to grow independently of their Little Valley relatives.

Obtaining the "XX" and the Move West

The legendary XX Tested mark originally belonged to the Case Brothers Cutlery Company. It represented a strict quality control system: one "X" stamped after the first heat-treatment, and a second "X" after tempering. Following a devastating fire that destroyed the Case Brothers plant in 1911, the trademarks and assets were eventually transferred to W.R. Case & Sons in Bradford. This critical move brought the "XX" legacy into the modern era.

Around this same time (1911), H.N. Platts developed health issues, specifically silicosis from years of inhaling factory dust. Seeking a drier, healthier climate, he and Debbie Case moved west to Boulder, Colorado. There, they founded the Western States Cutlery and Manufacturing Company. This established the legendary "Western" brand, expanding the Case family's influence and becoming famous for robust fixed-blade hunting knives and military gear.

The "Case XX" Family Tree: An Intertwined Cutlery Empire

The history of 20th-century American cutlery is essentially a history of the interrelated Champlin, Case, and Platts families. Here is exactly how the most famous brands tie back to the Case lineage:

• Cattaraugus: The original "alma mater" where the four Case brothers first learned the trade under their brother-in-law, J.B.F. Champlin.

• Platts (C. Platts & Sons): Founded by Charles Platts (a master cutler from Sheffield, England, hired by Champlin). His son, H.N. Platts, married Debbie Case and brought the family's renowned manufacturing expertise directly into W.R. Case & Sons.

• KA-BAR (Union Cutlery): Following disputes at Case Brothers, Andrew Case left the company and eventually became a minority owner of the Union Cutlery Company (KA-BAR), bridging the Case family directly to another legendary American military brand.

• Crandall Cutlery: Herbert Crandall married Mary Theresa Case. He ran Crandall Cutlery until moving to Bradford, PA, around the same time W.R. Case & Sons relocated there. The Crandall brand and its exquisite, highly sought-after designs were eventually absorbed by Case.

• Kane Cutlery: Another splinter from the original Case Brothers. John D. Case left the original firm to establish John D. Case & Sons (the Case Cutlery Co. of Kane, PA) alongside his three sons, keeping the family trade alive under a new banner.

• Kinfolks: Literally founded by kin—cousins Dean Case, Russ Case, and Tint Champlin. It was launched specifically to help W.R. Case & Sons and Cattaraugus meet the booming production demands for fixed-blade knives, ensuring the pocket knife factories wouldn't get bogged down.

• Robeson (ShurEdge): A fierce competitor that became deeply tied to the family when cousin Emerson Case took over management. He guided Robeson through its highly successful World War II military contract era and later continued the Kinfolks brand under the Robeson umbrella until the 1960s.
