Spanish Machete Sword?
 

I've had this large knife/small sword for a little while now, but I've only just added the end of the grip, which was missing. I fabricated this from oak, but painted it black to match the other part of the grip, which is a type of resin?
The blade has ....... REFINADO stamped into it, which I believe is Spanish for REFINED, as in 'Refined Steel or Iron'?
The blade is 18 1/2" and the knife is 23" overall.

There is a faded word before REFINADO; perhaps ACERO (steel) ? certainly not HIERRO (iron) ...

Hello

I think it's a machete used by the Spanish cavalry in the war in Cuba

Thanks guys. yes, looks to be ACERO (definitely ERO at the end)
I'll have to look up the Cuban War!
