Abstract
A stake driver having a first rod that has at least one solid end for driving a stake. The other end may be pointed. A second larger diameter rod is slidably insertable over the first rod. One of the open ends of the second rod is located over a stake. Then the first rod is moved upward to allow the stake to be encircled by the open end of the second rod. The end of the second rod may be slotted to accomodate a rectangular stake or marker fastened to the top of the stake. With one hand grasping the second rod, the other hand lifts the first rod and then releases it so that the first rod can free fall and drive the stake into the soil. If additional force is required to drive the pointed end of the first rod into the soil, a third rod is slid onto the second rod and screwably connected to it. The invention includes a removable shovel made from a fourth rod with a shovel blade secured to one end of the fourth rod which also can function as a surveying reflector support, with or without the shovel blade by means of a threaded member connected to the end of the fourth rod.
