✅ SOLVED 2" pin

[deepseeker3]

This item is 2 inches long. The shaft is magnetic, but no rust, so must be high carbon. The bulb at the top appears to be brass, with a knurled edge. I suspect a part of a tool, but it is not threaded to screw into anything.

Any ideas?

JKicker nailed it I think.

Scratch awl for metal. Basically the same as metal scribe tool.

I think I'm going to vote for the scribe tool hypothesis...

Yup, looks like an awl of some sort, I would have expected it to be threaded if it was to be part of a square.

Videos I have looked at say this is the first part of a square to be lost, and this one is certainly a good example of one that would disappear quickly!
