This is a vintage / antique, made in England Brown’s rag rug tool (bodger). It measures 6.5 inches long, and has been loved but is still in good shape to be used for your project. The spring mechanism works fine. There is some wear to metal as can be seen in photos, but it is smooth and there is no soiling or flaking. I believe it is slight oxidation or tarnish or just discoloration of some kind. But, it is clean and smooth, and can be used as is. Shipped with USPS Ground Advantage. Thanks for eBaying with me.
