The 2025 Lib Tech E. Jack Knife is a board that Eric Jackson can truly say suits his riding style perfectly. He grew up riding the Mammoth park then transitioned to riding everything steep and deep he can find, and his board is designed to handle it all. With C3 Directional camber and a medium stiff flex for loads of pop, edge hold and stability, riding away from giant landings and big drops aren't a problem. Added basalt absorbs vibrations from fast riding, and the lightweight tip and tail make getting those spins around easy. A serious board for serious riders!
