Bought a Sager Chemical, Puget Sound pattern axe with a 40 inch handle at a local flea market. Had never seen a Puget sound axe before. It appeared to have been laid on its side and struck with a large hammer. Perhaps to tighten the handle? It has a depression in the sides of the eye. I obtained a 40" handle for it. I found out that the eye is smaller on the straighter side of the axe head - the side away from the user. Very strange! Is this normal for these axes? I also saw pictures of several of these same type of axe heads on E-bay with the same depression in the side of the eye. Was bending the sides of the axe eye a common method of tightening the handle?
