William W. “Bill” Harsey Jr., born in 1955 in western Oregon, comes from a family with deep-rooted forestry traditions that shaped his unwavering work ethic and love of craftsmanship. After completing his bachelor's degree at the University of Oregon in 1979, he devoted himself to the art of knife making, harmoniously combining raw functionality with sophisticated aesthetics in his designs. He has collaborated with renowned personalities such as Colonel Rex Applegate and companies such as Gerber Legendary Blades, Chris Reeve Knives and Spartan Blades. For them, he designed award-winning models, including the Applegate-Fairbairn Combat Folder and The Green Beret Knife. Harsey's designs, distinguished by precision workmanship and a deep understanding of user needs, have won wide acclaim among professionals and collectors alike around the world.

Spartan Blades - In 2008, in a historic barn in Aberdeen, North Carolina, two retired non-commissioned officers of the United States Army Special Forces - Curtis Iovito and Mark Carey - combined over 40 years of military experience to found Spartan Blades, a company specializing in the production of high-quality knives for both military and civilian use. Each knife, reflecting their constant pursuit of perfection, is carefully designed and made from the finest materials, such as CPM MagnaCut steel and titanium. Thanks to its collaboration with renowned designers, including William W. Harsey, Jr., Spartan Blades has won numerous industry awards, including the prestigious title of “American Made Knife of the Year” for the Spartan-Harsey Folder model in 2016. In 2019, following the merger with KA-BAR Knives, Spartan Blades expanded its production capabilities, introducing three product lines: Gold, Silver and Bronze, tailored to the diverse needs of customers. Today, Spartan Blades remains synonymous with excellence in the world of knives, combining military precision with the highest craftsmanship.

CPM MagnaCut – powder stainless steel produced in the Crucible® Particle Metallurgy (CPM) process, hardened to 60.5-62.5 HRC. The high vanadium content of 4.0% (V), molybdenum content of 2.0% (Mo) and niobium content of 2.0% (Nb) guarantee a level of precision and purity that is unmatched by more “conventional” steels. Specially designed and developed for blade production by Larrin Thomas, it meets all the requirements of knife enthusiasts. Thanks to CPM MagnaCut, it has been possible to create a steel that combines the unique properties of knife steels like no other. The result is a blade material that offers an extraordinary balance between wear resistance, strength and corrosion resistance. Currently, there is no other steel on the world market that offers a comparable combination of excellent properties. This unique steel is produced in the American steelworks of Crucible® Industries.

Vacuum & Cryogenic - the steel undergoes a specialized heat treatment process involving two key stages. Vacuum Heat Treatment the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the strength and structural integrity of the steel. Double Cryogenic Treatment: After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation changes the residual austenite into martensite, significantly increasing the hardness, wear resistance and overall durability. Thanks to these advanced processes, the steel ensures exceptional performance, offering both razor-sharp edge retention and extraordinary blade durability.

PVD (Physical Vapor Deposition) - the surface resistance of the blade and cutting edge is increased by vacuum deposition, which is used to deposit thin layers by condensing the vaporized form of the desired material on the surface of the workpiece. The coating method involves a purely physical process, such as high-temperature vacuum evaporation followed by condensation. The applied coating has a very high hardness, which significantly increases the blade's resistance to rust and abrasive wear.

Blade - with a classic Spear Point profile, coated with black PVD. The blade thickness in combination with the flat grind provides excellent cutting properties and high durability. The long swedge improves the piercing properties. The extension at the handle prevents the hand from sliding onto the blade.

Handle - grips made of Canvas Micarta composite, a material with extremely high mechanical strength and virtually complete resistance to weather conditions and chemicals, textured for improved grip. The contoured shape ensures a comfortable, secure grip even with wet hands. Forefinger groove on the front improves grip.

Sheath - made of kydex plastic in black. Prevents the knife from falling out and facilitates quick access. Compatible with the MOLLE standard, allows the holster to be attached under the M.O.L.L.E. (Modular Lightweight Load-carrying Equipment) system straps (Modular Lightweight Load-carrying Equipment) or carry it on a belt or on equipment. A set of holes on the edge allows you to adjust the way you carry it to suit your individual needs.
