Mexican knife.
 

This arrived in the same parcel as the Machete, fairly ordinary knife with some engraving on the blade, and carved horn hilt scales. Photo's a mix of my own quick and dirty from the phone, and the vendors better quality selling pics. The blade is of fairly thin flat steel with a decent spring like that used for a saw blade, and may very well be made from one. Total overall length, 32.5 cm. (13 inches).

Better pix than before.

Interesting example David!
Regardless of being modern, it is exemplary of the traditions of edged weapon in Mexico carried forth from the Spanish colonial period and still faithfully followed. What is always fascinating with Mexican knives is often the colorful inscriptions and meaningful phrasing etc. on the blades.
i.e. from the bite of this scorpion, there is no medicine. ..and others.

This example with eagle head is relatively modern, from the knife making centers in Guerrero. The needle point is what is referred to in Mexican parlance (on espada anchas as well) as 'scorpion' point.
