Here is a pre-owned vintage primitive cast or forged iron and wire metal jar opener wrench.  I cannot find any maker's information or markings, but believe it is from the early 1900s.  The handles show irregularities from casting or forging - clearly primitive.  It measures about 7 1/2 inches long and shows some dirt and light corrosion as well.   Please see pictures and ask any questions.
