Eric Glesser Design, Ultralight Front-Flipper Performance. Blacked out and butter smooth.

Building on the Mantra legacy, the fourth-generation Mantra 4 is a sleek, stylish folder with an exceptionally refined front-flipper mechanism. A tiny sliver of the blade’s tang stands proud above the handle’s spine, and a stroke of the index finger sends the blade swiftly into the open position.

Its full-flat-ground 8Cr13MoV blade is cloaked in a non-reflective black oxide coating and rides on low-friction ball bearing washers with butter-smooth action. Contoured G-10 scales over a nested stainless liner form the sturdy liner lock, and a reversible deep-pocket wire clip keeps carry discreet.
