hi manolo, how's the spine on yours?
mine is engraved, brass inlaid and fancy fileworked for about 2/3 the length of the blade spine.
the curved one i have (see the other flyssa thread from today) does not have any decorations on the spine & the brass is tacked on with a large number of flush tacks which are quite obvious, unlike the straight one where you need to look closely to spot them, and the guard is fairly flimsy sheet brass, the blade itself is quite thick, distally tapered, not like the wedding nimchas, and may be a transitional piece morphing from a real to a parade weapon.
