HHHuuummmmm! It's a Kasiser blade! Hhhhuuuummm! Some folks call it a sling blade! Best wishes, Carl Clildress HHHuuuummmm!
Actually, this looks like a bark spud. primitive without handle but used to harvest bark from newly felled trees. There were lots of tree varieties that produced medicinal or industrial compounds. These tools were used prolifically in my area where folks were harvesting oak trees. We had a tannery in our area and the oak bark was used in the tanning process. Hence the Name "Virginia Oak Tannery" or Votan.
