What is this?

[tom hyle]

Without specific reason to view it as such, I do not think this is Hindian or a spear blade.

For me the back notches are indications of European manufacture. Hindo blades like this are either more slender, triangular in cross section, or in the form used in katars. I am thus in the European camp.

I noticed on the listing pictures the pommel has two holes 180 degrees apart. It suggests to me that a pronged tool tool was used to tighten it.....further suggesting that the tang is threaded and why, perhaps the guard is the wrong way round (if it is indeed incorrect)...wrongly re-assembled? The hilt components have gaps and seem 'slack' perhaps a few are missing
Interesting dagger never the less
