Abstract: A “sod saver” tool for digging to acquire an object buried in the ground, and a non-metallic scraping tool utilized when carefully examining the soil. The sod saver tool includes a main cylindrical body rotated about its longitudinal axis for digging a substantially cylindrical plug of soil from the ground, the object being contained in the plug of soil, and a plurality of circumferentially-disposed resilient non-metallic fingers located at a bottom portion of the main cylindrical body. When the digging of the plug is being performed, the resilient fingers tend to spread radially outward from the longitudinal axis of the main cylindrical body, being deflected away from directly hitting and scratching the buried object, tend to generally direct the soil upwardly into the main cylindrical body, and tend to cause the plug to be substantially-compacted and cylindrical. The compacted plug may be easily reinserted into a hole in the ground.
