ANSWERED !
We have been searching for ideas about what this tool is over on Tool Talk. I have had it for a long time, and I think it was discussed on the Tool talk that went south in 2011.
Knife sharpener comes to mind, but the two "wheels" don't turn and appear to be riveted in to be stationary.
The toothed end is not an alligator wrench in my opinion.
Length is 4 1/2 inches and the body is stamped steel and plated.
Good guesses, wild guesses, firm ideas, anything ?
