A stunning piece of early French ironwork -- the French smiths were considered the best in Europe. Not quite sure of their use: they're too small for pipe tongs, the finger rings are ladies' or children's size, and the best grip is at the tips of the birds' beaks (don't you love those birds?) For tapestry, or needlework? Whatever. Just look at the form and the decoration, and you'll realize you're looking at a top quality piece of late medieval ironwork.
