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 passion for craftsmanship. After earning his bachelor’s degree from the University of Oregon in 1979, he devoted himself to the art of knife making, harmoniously blending raw functionality with refined aesthetics in his designs. He has collaborated with such renowned figures 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 craftsmanship and a deep understanding of users’ needs, have earned widespread acclaim among both professionals and collectors worldwide.

Spartan Blades - In 2008, in a historic barn in Aberdeen, North Carolina, two retired non-commissioned officers of the U.S. 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 top-quality knives designed for both military and civilian use. Each knife, reflecting their relentless pursuit of perfection, is meticulously designed and crafted from the finest materials, such as CPM MagnaCut steel and titanium. Through collaborations with renowned designers, including William W. Harsey Jr., Spartan Blades has won numerous industry awards, including the prestigious title “American Made Knife of the Year” for the Spartan-Harsey Folder in 2016. In 2019, following a merger with KA-BAR Knives, Spartan Blades expanded its manufacturing capabilities by introducing three product lines: Gold, Silver, and Bronze, tailored to diverse customer needs. Today, Spartan Blades remains synonymous with excellence in the world of knives, combining military precision with the highest level of craftsmanship.

CPM MagnaCut – a powder-metallurgical stainless steel manufactured using the Crucible® Particle Metallurgy (CPM) process and hardened to a range of 60.5–62.5 HRC. A high content of vanadium 4.0% (V), molybdenum 2.0% (Mo), and niobium 2.0% (Nb) guarantees precision and purity unmatched by more “conventional” steels. Designed and developed specifically for blade production by Larrin Thomas, it meets all the requirements of knife enthusiasts. Thanks to CPM MagnaCut, we have succeeded in creating a steel that, like no other, combines the exceptional properties of knife steels. 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 global market that offers a comparable combination of excellent properties. This exceptional steel is manufactured in the American steel mills of Crucible® Industries.

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

Blade - featuring a classic Drop Point profile, finished with a Stonewashed treatment that masks minor scratches incurred during use. The pronounced spine extends the cutting edge length relative to the blade length. The substantial blade thickness, combined with a high flat grind, delivers excellent cutting performance coupled with high durability. Bronze washers assist in opening the blade using dual thumb studs on both sides of the blade. To maintain full control over the blade, the blade spine features upper jimping, a serrated thumb rest. The entire unit is locked with the proven and popular frame lock mechanism.

Handle - made of 6AL4V titanium, it features beveled edge on the covers, eliminating sharp points. The surface is adorned with an artistic engraving depicting the Plague Doctor. The open-backed construction, without a typical backspacer, secured together with titanium spacer sleeves, facilitates cleaning. The simple yet robust construction guarantees many years of use. The edges of the handle feature jimping, which improves grip. The pivot is adorned with a designer screw, and all fasteners (screws, clip) are gray. A reversible (right/left) titanium clip, decorated with an arrow motif, allows the knife to be carried in the tip-up position. Above the clip is a hole for threading a lanyard.
