"This ax XIX century has a thin blade and sharp sharpening angle." So I asked about the angle of sharpening -- "25 degrees?"
Answer, "Less than 25 degrees."
So my recently acquired (from eBay) Russian ax is at the tool sharpener for a 20 degree edge. I'm betting that a Russian cooper
would have no need for a side ax.
