Keep Finding These at Cellar Holes! What are They?

[FreeBirdTim]

This is the third one of these iron relics I've found at old cellar holes. Looks like they may have been attached to a wooden handle, but what were they used for? Any guesses would be appreciated.

looks similar to the metal piece for a scythe handle, the one that comes off the main wooden shaft. yet they are beefier then the ones I usually find, not sure if they might be older style or something completely different.
