[Philip]

Certain elements remind me of what I've seen on a number of Korean swords of the latter Joseon period (18th -19th cent),
1, The style of grip wrapping, sometimes with even wider braid.
2. Simple sleeve-like ferrule and pommel of rather thin metal
3. Radiused edge at the tip without the yokote or perpendicular delineation at the the apex of the typical angular kissaki on a shinogizukuri configuration blade.
4. The very narrow spine created by a marked taper of the blade cross-section above the shinogi ridge. Perhaps coincidentally, I've seen an identical cross-section in a Bukharan saber in the Moser Collection, in profile the blade looked almost double edged in that extreme example. 'Don't know if it's a continental affectation, although a couple of Chinese examples have come to my attention over the years; they are not common and the Bukhara manifestation is the only instance of that type I've seen so far from that region.
