3.5 Inch, AUS-8 Steel Blade Assisted Opening Quick-Reverse Clip The PDK series of knives is the result of collaboration between law enforcement officers, ASP&';s product designers and knife engineering and manufacturing experts. Their goal was to create a practical, tough and dependable knife specifically for day-in, day-out police use. A tool of excellent quality, yet affordable for any officer. The Engraver&';s Edition series features five exclusive embellishments, applied to the black blades of our original flat grip, Classic Folder PDK. The designs were created by our master engraver, and meticulously crafted in our state of the art, in-house laser engraving facility. The PDK features a 3.5a*? drop point a**flippera*? blade design with fast, positive assisted opening. The blade is crafted of highly corrosion-resistant, easy to maintain AUS-8 stainless steel. A liner lock makes it safe and easy to release and close the knife. High-quality, textured G-10 scales (grip panels) provide a sure grip, and our signature Shark Fin jimping adds solid control. PDK knives feature our unique, quick-release pocket clip system. Reversing the clip for right- or left-pocket carry is as fast and simple as using the double lock pin on a handcuff key (not included) to release the clip lock, and snapping it into the slot on the other side. No tiny screws to use (or lose). Finishing touches include a Thin Blue Line tribute spacer in the spine of the knife, and a die struck ASP Eagle medallion mounted in the grip.table.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }
