Sig Sauer knives are designed and manufactured by Hogue at their Henderson, Nevada facility. The collaboration produces knives that complement Sig Sauer firearms platforms in both design language and intended use. Every SIG-branded Hogue knife is Made in the USA.
The K320 is the primary SIG knife platform — a 3.5-inch ABLE Lock folder in S30V stainless steel built to pair with the Sig Sauer P320 pistol family. The manual K320 and push-button K320A share the same frame architecture across multiple sub-lines. The Nitron series features grey or black polymer frames. The M17/M18 series runs coyote tan polymer with matching PVD blade finishes and partially serrated options. The AXG Scorpion pairs FDE aluminum frames with G-Mascus green G-10 inserts and is available with partially serrated blades. The AXG Classic runs matte black aluminum with walnut wood inserts. The AXG Pro features black aluminum with black G-10 inlays and Cerakote finishes. A carbon fiber K320 variant is also available in both drop point and tanto profiles.
The K365A is a compact push-button deployment folder in CPM MagnaCut designed as a companion to the Sig Sauer P365 pistol platform. It runs a 2.75-inch clip point blade with a polymer frame in black, grey, and coyote colorways.
SIG-branded variants of other Hogue models are also available in this category, including the SIG Counterstrike, SIG EX-01, SIG EX-A01, SIG X5, SIG EX-A05, SIG A01 Microswitch, SIG X1 Microflip, SIG EX-F03, SIG Compound, and SIG EX-T01 Tomahawk. These carry the Emperor Scorpion or Tactical finish schemes with black G-10 handles, FDE or grey blade finishes, and SIG medallion accents.
