The Hogue SIG K320® Manual Folder (M17 & M18) is a premium EDC folding knife built to match the legendary SIG Sauer P320 M17 and M18 pistols, delivering the same military-grade reliability in the palm of your hand. The 3.5" tanto blade is crafted from CPM S30V stainless steel — one of the toughest blade steels on the market — cryogenically heat treated to a hardness of 58–61 HRC and finished in a bold Coyote PVD coating that resists corrosion and looks as sharp as it performs. Weighing just 4.18 oz and measuring 8 inches, this knife is light enough for all-day carry without sacrificing the toughness you need in the field. The ambidextrous deployment window pairs with Hogue's patented ABLE Lock® (Ambidextrous Bar Lock Enhanced) for a secure, one-handed open and close, no matter which hand you favor. The Coyote Tan Polyamide Nylon 12 glass-fiber reinforced polymer frame features the same P320 stippled texture you know from the grip, giving you a confident hold in any condition. A deep-carry, louvered pocket clip rounds out the package with flexible tip-up or tip-down carry for both right- and left-handed users — so whether you're gearing up for the outdoors or adding a serious collector's piece to your lineup, the K320® Manual Folder is built to move with you.
