Every collection has some junk anf these are those pieces from Andy's collection. While I have classified these as junk they are also interesting in that they are examples not seen elsewhere.

The piece at the top is a tunnel stake with the shank cut off or a short block welded on for clamping in a vise.

In the middle is an "anvil stake". Short versions with no shank (just the taper) are called "anvils". The long shank makes it a stake according to Hasluck. This stake has steps of notches filed or ground into the shank. These are probably gauging marks of some sort.

The little beakhorn stake to the left appears to have been a larger stake that was cut down and modified for use in a vise or blacksmiths anvil.
