Have recently acquired these two small Brazilian daggers called Faca de Ponta (pointed knives), they coming from Northeastern region of Brazil and also called "Facas Nordestinas".

I think that the both knives are from the first half of the 20th century.
Here the pictures from the first one, sadly without it's leather scabbard. It's 10" long overall with a blade from 6 1/4".
