Found these at one of my sites. The larger piece(top right) seems to be a scraper of some kind with a engraver tip. The two on the bottom are broken pcs. But the point in the top left is what I am wondering about. It is flat on the other side.
Well I guess from the viewings that nobody wants to dive into what this point is. My bet is a tip off something that they tried to rework into a point?
