Spanish colonial short sword?

[Yvain]

Hi all!



I found this interesting short sword for cheap some days ago. It is very similar to some other short swords identified as Mexican or Spanish colonial, including on this forum (see the last three pictures).



It seems well made, but surprisingly the blade isn't shaperned (and I don't mean dull but truly unsharpened). However the blade is peened, flexes a bit, and seem to be wide at the guard. It feels rather balanced and lively in the hand.



So far I have three guesses :


-it's a repro : it would surprise me considering this is a rather obscure weapon, and the general quality seems too good for a repro


-the blade was meant to be sharpened by the buyer : doesn't seem to weird to me, I think it was done for some tools


-the blade has been ground later in its life : possible, but I don't know why someone would do that


Would love to hear what you think about it! 🙂
