Looks like the handle of a knife... And the glint of possibly another on his opposite side but it's not very detailed. Behind him is a painted scenic backdrop of what looks like a lake or shoreline scene.
No ID or location, but the backdrop might help pin down the photographer. In person this tintype should look at least as good as image 2 when viewed in proper lighting. In very good antique condition with oval shaped mat abrasions, but NO bends, and no issues in the main viewing area. The case is complete and intact with light wear and taped spine.
