I have recently aquired Unsal Yucel's 'Islamic Swords and Swordsmiths' (it arrived in the post yesterday
). Although I had seen an Arabic version of it in Cairo many years ago.
Anyway Yucel has several pictures of 15th century swords made by smiths with the title or surname 'Al-Misri' which means 'The Egyptian'. This would indicate that the makers of these swords were Egyptian or at least had Egyptian ancestry.
