Wow. What a cool sword.
Note that the guard seems to be shaped as the cuff of a likely ceremonial vestment of some kind. Is there any known gesture, used in religious or lodge practice, perhaps, where one grips one's own left hand in the manner one grips this hilt?
I had a straight Spanish cavalry "saber" with a spine fuller. Beautiful sword. Very rust-pitted, but I sharpened it up for a friend who needed a sword.
Love the spine fuller. Love the peaked spine. I love that spine they do on pesh kabz and salawar yatagans sometimes, where the spine has its own little round-topped midrib......

I love the spine groove....
Is the hilt cast on to the tang on this sword, or how is it attached, if you don't mind answering?
