Mystery mining tools found in or around the fluorite mines of Crittenden County, Kentucky. Does anyone know what these are? When recently at the Ben E. Clement Mineral Museum during the tour, the museum manager showed these tools and asked if anyone knew what they were. Three different sized tools, one is in a circle and two others were pill shaped. Inside the tray tools are rows of spike like protrusions. Circular tool is about 4 inches in diameter (10 cm), longest pill shape tool is about 12 inches long (30 cm) and the shorter pill shaped tray is about 10 inches long (25 cm).
Here are some other tools that were on display.
