I'll qualify that only slightly as there seems to be a "love it" (most of us) vs "take it or leave it" dichotomy, which is kind of interesting in itself. No one hates it.
To the extent that one can define types at least in my mind, the Sebenza is the ultimate *utility* folder. It is expensive by many standards, there are good knives for much less money, but none of them seem to have nearly the over all feel of inner strength (and I mean the knife, not the user) possessed by the Sebenza. Its a little like 4 wheel drive, a feeling difficult to describe, but definately noticible when you actually experience it.
People who are not looking for a basic utility geometry (for example they want a "fighter", or some other more radical shapes appeal to them) do not seem to fall in love with the Sebenza, though even they usually concede its over-all strengths within its type.
