In layman’s terms, the bent anchors on each side, these should be a sharp 90 bend on real, repos have a round edge.
on the inside, you see two rivets near the lower teeth, another modern approach, no rivets in original, and harder to differentiate from pictures but it’s painted and not urushi and the odoshi is not laced properly.
these are the first impressions, but it’s completely modern.
