The Lib Tech EJack Knife is the hard-charging directional freeride machine designed in collaboration with backcountry powerhouse Eric Jackson. Built for seep lines, massive drops, and high-speed precision, this board blends traditional camber power with modern float and versatility. Its mildly tapered tail and spoon nose enhance powder performance, while the aggressive C3 camber provides edge-to-edge control and maximum pop. With eco-conscious construction, rugged materials, and serious tech throughout, the EJack Knife delivers stability, control, and confidence wherever the mountain leads. From groomers to natural booters and deep powder chutes, this board is made to push boundaries
