Hogue Sig Sauer K365A Automatic Knife M17/M18 Coyote Tan PVD Magnacut/Polymer AUHG16331

Built as a true companion to Sig Sauer’s revolutionary P365 platform, the Hogue Sig Sauer K365A automatic knife is a purpose-driven collaboration between American-made knifemakers and one of the most respected firearms manufacturers in the world. Every detail mirrors the mindset behind Sig’s pistols, from compact dimensions to decisive deployment, creating a knife that feels like it belongs alongside your carry rather than merely accompanying it. Designed by Scott Bruhns and made in the USA, the K365A reflects the same emphasis on reliability, control, and refined function that defines both brands.

At the core of the K365A is a 2.75-inch CPM MagnaCut clip point blade, heat treated to a hard-working 62–64 HRC for exceptional edge stability and corrosion resistance. Each blade is finished in Armor Black or M17 Coyote Tan Cerakote to perfectly match Sig’s Nitron, Tactical, and M17/M18 colorways. The side-opening automatic action delivers immediate, confident deployment through a triangular push button modeled after Sig’s distinctive magazine release, reinforcing the shared design language between knife and firearm. Hogue’s hand-sharpened and honed factory edge ensures it’s ready for real-world use right out of the box.

The handle is constructed from glass fiber reinforced Polyamide Nylon 12 and carries Sig’s familiar stippled texture, offering secure traction without hot spots during extended carry. With a closed length of just 4 inches and a weight of only 2.4 ounces, the K365A disappears in the pocket while remaining solid and controllable in hand. A deep-carry, reversible pocket clip with filler plate keeps the profile clean and adaptable for left- or right-handed users, while minimal hardware and thoughtful ergonomics maintain a streamlined, no-nonsense feel.
