Spyderco Endura 4 Emerson Opener Folding Knife – 3.8" VG-10 Blade

The Spyderco Endura 4 with Emerson Opener is a proven EDC and defensive carry folder built around a wave-shaped feature that deploys the blade automatically as you draw from your pocket. The 3.8-inch VG-10 steel blade combines edge retention with ease of sharpening, while the signature Spyderco round hole allows ambidextrous thumb deployment if you prefer manual opening. This full-sized folder is equally at home as a work knife or a backup defensive tool.

The FRN handle is textured for secure grip in wet conditions and features a reversible wire pocket clip for tip-up or tip-down carry. The back lock provides solid lockup under heavy use. The Emerson wave opener is designed to catch on your pocket edge during the draw, rotating the blade open in one smooth motion—no thumb required.
