Lamination Question

It is hard to tell for sure. What makes it look sandwiched to me are the lines of lighter color running to the edge just to the right of center. The first from the left looks like it might be a crack, but the second and third look like they are threads of the outer layer continuing to the edge, which would happen if there was a crease or other depression in the middle layer at that point that was filled with metal from the outer layer during forging.
