发明名称 Stake driving device and method
摘要 A stake can be driven into a surrounding terrain using a point drive system. The stake body is formed of a durable material such as plastic with a pointed bottom end and a top end which can carry a bundle of colored filaments. The stake body has a hollow interior bore extending from a top end opening downwardly to a bottom end opening. The hollow interior bore of the stake receives a pointed shaft driver which allows the stake to be driven into even difficult terrains in point drive fashion.
