Description:
FIELD OF THE INVENTION 
       [0001]    The present invention is directed to a multipurpose earth tool that includes a handle, a head, a fastening system, and at least one interchangeable tool to enable a person to perform a variety of tasks on outdoor vegetation with ease and minimal effort. 
       BACKGROUND OF THE INVENTION 
       [0002]    Persons using a hand tool to garden, excavate, maintain outdoor vegetation, and the like, often wish to perform such tasks with ease and minimal effort. They also may wish to have the ability to perform multiple tasks using a single hand tool without having to use multiple tools. Further, a person may wish to have a single hand tool that is able to withstand extreme use and force without breaking, cracking, or becoming unusable. Additionally, they may wish to have a single hand tool that is easy to store in more than one manner. However, most persons who wish to perform tasks, such as gardening, excavating, maintaining outdoor vegetation, and the like, must often bend over to perform such tasks or use a great amount of energy and repetitions to perform such tasks. Also, a person who wishes to perform tasks, such as gardening, excavating, maintaining outdoor vegetation, and the like, must either use several different hand tools to complete the tasks or use a single device. However, one problem with any single device tool that currently exists is a person must take the time to attach and detach different tool attachments. A problem with the current multi-purpose hand tools that exist are the inability to perform tasks, such as gardening, excavating, maintaining outdoor vegetation, and the like, effectively because of an imbalance of the garden tool and the weight of the garden tool. Another problem with current multi-purpose hand tools is the inability to withstand extreme force and use without breaking or cracking. Finally, current multi-purpose hand tools create damage to surrounding ground, plants, and vegetation and cause unnecessary damage. 
         [0003]    Therefore, there is a need for a multi-purpose tool, where a person may perform tasks, such as gardening, excavating, maintaining vegetation, and the like, with ease, minimal effort, and one single tool. 
       SUMMARY OF THE INVENTION 
       [0004]    The present invention provides a multipurpose earth tool comprising a head, a first tool device, a second tool device, and a third tool device; a handle attached to the head; a fastening system mounted to the handle including a first stabilizer cap, a second stabilizer cap, a sleeve, and an attachment means; and an interchangeable tool attached to the handle. 
         [0005]    The present invention provides a fastening system mounted to a handle including a first stabilizer cap, a second stabilizer cap, a sleeve, and an attachment means. 
         [0006]    Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
