This struck me an especially lovely old forged iron flint striker, used for starting a fire. I am not certain exact age, but it certainly looks and feels quite old to me. Beautiful form, great surface, satisfying in the hand. I might be inclined to wear this as a pendant around my neck when wanting/needing to feel powerful!
3 1/4" x 1 1/4". Surface wear and aging as evident, very much to the good I think.
