Curtiss Custom Knives LLC – F3M-WHFL-ST/SL – F3 Med Flipper Slim – Folding Knife – CTS-XHP Stonewash Wharncliffe – Titanium – Natural

Description

The Curtiss Custom Knives F3M-WHFL-ST/SL, also known as the F3 Medium Wharny Flipper Slim, is a precision-crafted folding knife that blends bold styling with elite-level performance. This mid-sized variant of the Curtiss F3 series stands out with its slimmed-down profile and aggressive Wharncliffe blade, making it a highly functional everyday carry (EDC) tool that doesn’t sacrifice strength for sleekness. This particular model is equipped with a 3.50″ blade made from premium CTS-XHP stainless steel—an American-made alloy known for its excellent edge retention and corrosion resistance. The blade rides on caged pivot bearings, ensuring smooth deployment with a satisfying, reliable flipper action. The frame is constructed from .160″ thick titanium slabs finished in a rugged stonewashed texture, offering both durability and a refined industrial aesthetic. With an overall closed length of 4.5″ and a total open length of 7.75″, the F3 Medium balances perfectly in hand and slips easily into your pocket without unnecessary bulk. At just around 0.5″ thick, this “Slim” variant provides a more pocket-friendly feel while maintaining the toughness and rigidity the F3 line is known for. One of the key innovations featured in this knife is the S.P.O.T. (Stop Pin Over Travel) Pivot System, which enhances lockup strength and prevents over-travel during lockbar disengagement. It also comes with a hardened D2 steel lockbar insert, ensuring long-term reliability and wear resistance at the interface between blade tang and lockbar. All hardware, including pivot, screws, and standoffs, are stainless steel for optimal corrosion resistance and long-term performance.
