CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application claims the benefit of U.S. Provisional Patent Application No. 61/392,543, filed Oct. 13, 2010, the entire disclosure of which is incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The invention relates generally to flatware and more particularly to devices for providing flatware with interchangeable handles. 
       BACKGROUND 
       [0003]    Flatware generally includes a handle and a working end extending therefrom. The working end is the portion of the flatware used for cutting or otherwise manipulating food. Some flatware is made from a single piece of material such as aluminum or stainless steel. Other types of flatware include a handle component which is formed of material different from the working end. Such handles may be formed of wood, plastic, ceramic, and other materials. In such cases, the handle is typically formed by a process, then permanently attached to the flatware. 
         [0004]    It is often desirable for flatware to have a decorative nature, so that it will be aesthetically pleasing when it is used in conjunction with a particular table setting, room décor or occasion. It is desirable for some to have their flatware match their plates, table linens, holiday theme, or the like. Unfortunately, it is not always possible for a single flatware set to match every occasion or table setting. In such cases individuals must obtain multiple sets of flatware, each having a different decorative appearance. Not only is this an expensive undertaking, but it requires storage of a significant number of flatware sets. 
         [0005]    Moreover, flatware handles must be sturdy, so that the handle does not separate or break away from the working end. 
         [0006]    Thus there is a need in the art for an inexpensive alternative to maintaining multiple sets of flatware, wherein such flatware is of a sturdy construction.
