From my own usage, I would say that the Umnumzaan, Mnandi, Hollow Handles (discontinued), Pacific, and all Sebenzas ranging from the initial ATS-34 models through the current S35VN 21 and 25 carry a fit and finish that is second-to-none. So I imagine all of their knives carry a similar level of notable quality, although I cannot speak to models not listed above. I think you hear discussion on the Seb most mainly because it is hugely popular for a knife in that price range.
