ABSTRACT:
The present invention comprises a tamping tool comprising a shank and a blade, with the blade having various arrangements of wear-resistant material affixed to the face of the blade by means of brazing, soldering, gluing or other method. Additionally, some arrangements of the tamping tool have a wear-resistant tip inserted into a groove in the end of the blade. The tamping tool of the present invention reduces wear, providing an increased life and increasing the time intervals at which it becomes necessary to replace the tamping tool.
