From what I can tell Okapi is a POS folder made in South Africa, so this is fairly clearly a copy, but given the South African reputation it’s probably better than the original.
A thin folder with a 16cm blade? That’s a big one.
I have one made in Africa but, I do not trust the lock. The steel seems top notch & holds a very sharp edge. These were intended to be sold to Africans with very little disposable income. Its a decent cheap knife IMO.
