Hey, as an Argentine and a lover and user of traditional Argentine knives, let me tell you that those Mission knives are aweful. We have excellent custom makers that create excellent quality pieces, but sadly are only known to a few. I mean, for around $80 you can get a top notch hand forged blade, or a custom folder.
I'm sorry to burst your bubble, but this is like real khukris vs tourist khukris. I wouldn't use that Mission knife very hard, and I wouldn't expect to find it hanging from the belt of any Argentine "paisano" (there are no more gauchos) that expects hard work.
They do have a decent fit and finish for their price, and they will work for light utility tasks. If you don't mind, can you tell me how much you paid for it?
