Spanish(?) Machete Sword with horn grips

[dandon80]

Good afternoon everyone,

For my first post here I'd like to offer up this interesting 19" (overall) machete type knife with horn grips and a fullered blade which becomes double edged. It's a quality piece with good steel and craftsmanship although its stitched leather sheath is not so reflective of that anymore!

Perhaps the most interesting quality is the stamped "K&F" trademark which is yet to be identified despite my efforts. Possibly a German blade on a Spanish Colonial Machete?

I have found similar examples here https://drouot.com/en/l/20070558

Any thoughts and opinions welcomed, and thank you!
