This could possibly be a spoon auger or sometimes called a spoon bit. These can date back to before the 1700’s. Some wood guys still use them (even seen one used on The Woodshop on PBS once). A friend has one with a twist on the other end like your find and uses it to pull the wood chips out from the hole (The disadvantage was that they didn’t eject chips like twist drills). Most were forged so they came in all shapes and sizes.View attachment 1872918View attachment 1872919View attachment 1872920
It looks like a gouge. The handle is missing and the end appears to have been hammered on? Another thought. Gouges usually had long handles, the hook looking "may?" have been for hanging?
