Spyderco Mantra 4 Features The Spyderco Mantra 4 builds on the legacy of the Mantra series with a fourth generation design centered on an exceptionally refined front flipper opener. In the closed position only a tiny sliver of the blade s tang stands proud above the handle spine giving the knife a minimalist snag free profile for pocket carry. A stroke of the index finger against the textured flipper surface propels the blade swiftly and reliably into the open position every time. The 3.34 inch blade is full flat ground from 8Cr13MoV stainless steel and finished in black oxide balancing a keen edge with corrosion resistance. The blade also features Spyderco s trademark round hole along with a liner lock mechanism that keeps the blade secure once opened. It rides on ball bearing washers which deliver an ultra smooth low friction action that makes one handed opening and closing effortless. The Black G-10 handle provides a stable textured grip surface that performs well in a variety of conditions without adding unnecessary bulk. At 7.5 inches overall the Mantra 4 is compact enough for daily carry while still offering a full size blade for everyday cutting tasks and it is for sale at GrabAGun for collectors and EDC users alike.
