This is wedge, and it has letters embossed on one side. “Endurance” is the maker’s mark. Originally thought item was a hatchet head or shaping tool but after investigating with Stu McNolty the wear marks on item point to its use as a wedge. Stu believes it was used to wedge a mill or boiler to level it, in a logging operation. Johnny Jones found an identical item with maker’s mark “Endurance” at the Parkhurst site which was a tie/pole mill in ca. 1920 The item is well-used. It was found in the Sam Jim house.
