Abstract
This invention is a tool for either inserting the stem of a flag or marker in soil or rocky terrain or providing a hole therein of sufficient size to receive the stem of a flag. The tool is made up of three main components, these being an inner rod, an outer pipe and a pair of collars attached near the ends of the inner rod. The outer pipe is positioned between the two collars. The inner rod is notched on one end to facilitate inserting the tool. To insert the flag, the user places a bend in the flag stem and then places the stem inside the notch. By pounding down on the lower collar (which is attached to the inner rod) with the outer pipe the notched end and flag stem are driven into the ground. When the flag has been inserted to a desired depth, the tool is extracted leaving the flag inserted in the ground. Alternatively, to insert the flag the tool is used to create a hole of sufficient size wherein the flag is then inserted.
