Abstract
A degradation pick of the type used in such fields as road milling, mining, and trenching to engage and degrade tough materials such as asphalt, concrete, and rock may comprise a body attached at one end to a substantially cylindrical shaft. A hardened tip may also be attached to the body opposite the shaft. The hardened tip may comprise an axis offset from a central axis of the shaft. Such a degradation pick may be secured to an exterior of a rotatable drum or continuous chain so as to be repeatedly brought into contact with a surface of a material to be degraded. The body may comprise a protruding spine adjacent the hardened tip and opposite a direction of travel of the hardened tip when transported by a rotating drum or continuous chain.
