How thick is it? It looks like a 'turner" you would use it to turn a collar {or something} right side out. After you sew a corner, you poke that into the corner to turn it. The modern version is Dritz Point Turner and Seam Creaser for Sewing Products. I don't know if yours is strong enough, or thick enough. Of course, it could be something else entirely. It's really neato. I love old sewing stuff.
