IMHO The so-called spike
in the club that started this post looks to me to be the drive end of a bit (drill bit) that was used in one of the old hand cranked braces (hand operated drill) used up until electric drills became readily available. The pictures below are from Woodworking Magazine, Wikipedia and one from the auction cropped to show the spike better. If I remember correctly these items in this form were not invented until the early 19th century.
