A somewhat unusual faca de ponta for sharing

[Sajen]

I won this faca de ponta recently at a German auction. It's a somewhat unusual example since it doesn't show the usual brass or with other metals plated ricasso, also the blade shape is a little bit unusual.
It's 35 cm long inside scabbard, 34 cm without, the blade is 23,2 cm long.
One picture shows it together with some other long facas from my collection.
