chilean knives (?)

[kronckew]

the middle one is a corvo chileno, which is a much more distinctive form than the other two, which are more generic and thus i'd not venture a guess on those.

see Linky





p.s. - corvus in latin means 'raven', used specifically for the boarding ramp at the front of a punic era roman fighting galley with it's beak-like hook at the front. the corvo takes it's name from it's also beak-like appearance.
