DESCRIPTION

Designed with components from some of our most versatile models, the Army Knife carves its own path with speed and precision. We started with the flatter rockers and straighter rail lines of the 3DF for quick down the line speed. Its nose comes from the White Diamond giving the Army Knife that same comfortable yet ready for performance feel that makes the WD so famous. With hips from the Modern 80s, not only do they look rad, they act as pivot points on the rails and aid in the reduction of the tail area. The Army Knife’s pulled in tail is complete with the tail block from the nimble Black Diamond for extra sensitivity and easy turning. Most of us need more than just a sharp blade. The Army Knife is the everyday wave multi-tool.
