Excellent examples. Appears to me that the smiths who assembled these swords did not use this form alone, as the engraving style reminds me of a crude saif I once had that followed the exact patterns but of a more nejdi style hilt. The engraving reminds me most of the silver example owned by Artzi shown in the gallery.
