Spyderco Swick 6 Fixed Blade Knife 2.73in LC200N Plain Wharncliffe Blade Boltaron Sheath Black G10 Handle. Its most distinctive feature is a Perrin-inspired index-finger hole that locks the knife into the users hand for superior grip security. Sized for a mans hand the 1.03-inch-diameter (26.1mm) hole is flanked by a full-flat-ground Wharncliffe blade and a full-tang pistol-grip-style handle. Concealed internal pins secure a pair of peel-ply-textured scales to the handle and a strategically placed section of jimping (textured grooves) on the spine provides a non-slip thumb ramp. Made from ultra-corrosion-resistant LC200N the Swick is accompanied by a custom-molded Boltaron sheath with a fully adjustable G-Clip and breakaway ball chain to offer a full spectrum of carry options.
