"Elgood also notes on p.86 that HH Sultan Ghalib Al Qu'aiti described to him how magnetic quality found in some dagger blades raised the esteem of the blade. He notes that the very best janbiyya and nimsha blades were imported into the Hadhramaut from Hyderabad where they were made. These blades were referred to generally as 'Haiderabad'"
As far as I am concerned you have answered to my satisfaction the question on why the blades were magnetic in the first place, it was a desired quality by the makers and users of the blades.
I share with you the "speechless" comment you made, with folks like Jim
with his never ceasing quest for knowledge and the desire to share it is what this forum is all about.
Now we just have got to keep Jens
from posting for a day or two all these hard questions and let us absorb the good information.
