The Spyderco Persistence Folding Knife is aptly named for its designed durability and versatile functionality. This compact version of the well-loved Tenacious model features a meticulously milled black G-10 laminate handle, aimed at reducing fatigue during extended use. Inside the handle, skeletonized steel liners bolster rigidity and strength without contributing to extra weight. The blade, crafted from 8Cr13MoV stainless steel, boasts a full-flat grind, ensuring it holds a sharp edge over time and providing exceptional cutting power. Opening and closing the knife is remarkably easy, thanks to the oversized round hole, strategically placed for smooth one-handed operation. When not in use, the four-way pocket clip allows the knife to be carried in a variety of positions—tip-up or tip-down, and suitable for both left- and right-handed users. Spyderco once again demonstrates its commitment to quality and innovation with features such as a reliable LinerLock mechanism, screw-together construction, phosphor bronze washers for fluid movement, and jimping on both the spine and liner for enhanced grip and control. Measuring 6.8 inches overall with a 2.75-inch blade and weighing just 3.3 ounces, the Spyderco Persistence is a compact yet robust tool. The knife’s design includes a 0.5-inch hole diameter and a three-millimeter blade thickness, reflecting Spyderco's dedication to creating ergonomic and functional tools.
