CURTISS CUSTOM KNIVES Curtiss Knives F3 Medium CTS-XHP Wharncliffe Non-Flipper Slim Folder WH/NF

The F3 titanium frame lock folder is a cornerstone design from Curtiss Custom Knives and delivers hard use cutting performance with rugged aesthetics. Dual slabs of blasted and tumbled titanium house the hollow ground CTS-XHP blade riding smooth on bearings at the S.P.O.T. system pivot for smooth, reliable operation. This slim non-flipper version comes with a two-tone Wharncliffe profile blade.

Brand new, direct from Curtiss Custom Knives.

Blade: The modified Wharncliffe blade comes with a slicing hollow grind with some belly for utility and a strong tip for piercing and detail work. The bearing pivot allows for smooth operation of the two-tone XHP blade via the dual milled pockets on the bright stonewashed flats. A compact choil and deep jimping provides solid control for safe use.

Handle: Dual slabs of blasted and tumbled titanium joined by a jimped partial back spacer form the handle with chamfered edges for comfort. This slim variant has slightly thinner slabs reducing the weight along with internal milling. The integral frame lock is smooth, solid, and secure. Includes zipper pouch, patch, sticker, and signed certificate of authenticity.

Carries via a right-hand titanium pocket clip.

S.P.O.T. Pivot System: Custom pivot hardware directly integrates an internal stop pin and lock bar over travel stop.

CTS-XHP: An ultra-high-carbon steel that was developed to combine the corrosion resistance of 440C and hardness of D2. It offers good hardness with toughness-edge retention balance, both being better than S35VN with easier sharpening. Corrosion resistance is closer to 3V than 440C, making it more of a semi-stainless.
