British or Indo Persian Blade?

[Hotspur]

All that is cast/crucible, is not necessarily classified as wootz. I wouldn't bother with etching it. It does look like crucible steel, as you can see the dentritic structure if enlarging the images.

There is a polished look of cast/crucible 18th and 19th century British blades that has kind of a fine sparkly look. My Wooley Deakin&Co blade has such a look and likewise a less polished yataghan I own. The yataghan blade regarded by some as "low resolution wootz" is simply a less figured and homogeneous crucible steel. The dentritic structure evident without the whoorls and patterning of fine wootz. A lot of fine wootz work a matter of how the cakes are processed/smithed.

Anyway, here is a segment of imaging from my yataghan blade, the Woolley blade hard to capture but sparkles in refracted light.
