Was in some of my granddad's things. Tip is very sharp. The blunt end is machined and not a separate piece screwed into place. You can see vague marks on that blunt end where a screw held it into a handle or attachment. There are no holes in it. I've had guesses from plumb bob to leather punch. I lean toward leather punch; if there was a removable handle on the end then I would think this was part of a set. Ever seen this?
