I grabbed this off ebay recently. It was going at a pretty reasonable price, and I just had to have it for the mystery factor.
I'm pretty sure this is a stake and not a hardy due to the tapered shaft and one other give away... The shaft is just under 4" long and the end is slightly mushroomed. ~4" is pretty common for a swage block.
The point isn't sharp enough to be for cut off, and is worn down more on one side. The bottom edge of the table appears well worn.
Any thoughts? It is just so odd, surely it had a specific purpose.
