Grinding Stone

The idiom "nose to the grindstone" was first coined in the 14th Century, when those of an idle persuasion had their snouts ground off as punishment and to serve as a warning to others. Whereas the grindstones referred to in those days were huge and found in flour mills, this grindstone is of a more intricate design. Compatible with drills and other handheld rotary tools, this grindstone attachment can be used to shape and finish a variety of metals, stone, wood, or your mother's thick juicy toenails.
