Description

This used Curtiss Knives F3 Medium Wharncliffe was built from the ground up to meet the demand for a hard-use, American-made folding knife with no compromises. Designed by Dave Curtiss, the F3 Series blends rugged construction with refined machining, resulting in a folder that feels purpose-built for real-world carry and demanding tasks.

This standard Wharncliffe configuration features a CPM MagnaCut blade, offering an excellent balance of edge retention, toughness, and corrosion resistance. The blade rides on caged bearings and utilizes Curtiss Knives’ patented S.P.O.T. (Smooth Precision Operation Technology) pivot system, a non-adjustable design that delivers fast, consistent action and solid lockup without concern for debris intrusion. A D2 tool steel lockbar insert adds longevity and reliability to the frame lock interface.

The 6Al4V titanium handle frames feature a blasted and dark stonewashed finish, matched by the titanium backspacer for a cohesive, industrial aesthetic. Thoughtfully milled jimping along the thumb ramp provides confident control without hot spots, a subtle detail that stands out with continued use. Even as a previously owned example, this F3 Medium remains a robust, precision-built folder that reflects Curtiss Knives’ commitment to durability and performance.
