Mystery sword - tourist/souvenir piece?

[Araña_del_Sol]

Hi all,

I recently obtained a sword I have not been able to place, it has a wide leaf-shaped blade but a constricted "neck" with small spikes near the hilt. There are somewhat faint V-shaped incisions along the center of the blade (hopefully visible in closeup picture). The hilt is wrapped in copper wire and has a fish tail pommel. Overall, the sword is quite heavy and very sharp. Unfortunately my search for a cultural/regional attribution has not turned up any matches, I suspect it might be a ceremonial item or possibly a tourist piece. Any insights on an ID would be greatly appreciated.

Overall length: 58.7 cm (~23 in.)
Blade width: 9.6 cm (~3.8 in.)
