A stake extraction implement for primary utilization with respect to stakes used for concrete forms. The stake extraction implement is composed of an elongate member, incorporating a handle portion and a curved portion, and a pivotally connected gripper tool, incorporating a pair of jaws. When a stake is to be extracted, the curved portion of the elongate member is placed upon the adjacent concrete form and the jaws of the gripper tool are aligned to rest upon the sides of the subject stake. According to the method of use disclosed, as a lever movement of the handle portion is effected, effortless extraction of the stake from the ground is made possible by automatic clamping of the jaws of the gripper tool onto the stake, the stake having been nailed to the concrete form notwithstanding. The stake pulling implement is structured to permit user selection of either a first class or second class lever mode of operation, and two types of jaw members for the gripper tool are disclosed.
