A wooden shovel worn on one side, and nobody knows what for
What it is
Ash, one piece, about nine inches wide, with the blade worn to about half thickness on the left side only over roughly its lower third.
The three explanations
Malt turning, lime spreading, and grain trimming. Each explains some of the wear and none explains the asymmetry.
What would settle it
Another one. If anybody has seen a second example, or a photograph of one in use, that would probably answer it in a sentence.
