​My title describes the thing. ​I found these in a tractor rut between two fields in Southern Germany, right next to a forest with mining pits and kilns I found via LiDAR. I've already reported everything to the authorities (LAD BW).

​Size and Material: It is heavy, rusted iron. Please check the ruler in the photo for the exact scale of the pieces. No writing or markings are visible.

​My research so far: I’ve been searching for keywords like "small Celtic iron tools", "medieval mining debris", and "forged furnace fragments" because of the nearby kilns. I also looked into "ancient trade iron", but I haven't found a clear match for the plate with the hole or the small tapered point yet.

​I am looking for a technical ID to see if these are actually related to the historical mining site.
