I got my Sebenza direct from factory, since I ordered it online. Sure there was a month or so waiting period (I didn't get anything fancy, just a plain large with dual silver thumbstud + matching backspacer) but it was worth it.
The Sebenza, like everyone else has said, exceeds all other knives in the quality of it's fit and finish, yet still maintains a level of simplicity that no other knife out there has. I wasn't around for the older versions with ATS or BG42 steel, but what I've got in my hands right now is probably the best knife I've ever owned.
When you've got the whole thing put together and push on the thumbstud, it opens smooth as butter, purposefully with that "bank vault" feel everyone raves about, and the sound of that "click-lock" has a kind of a deep and much more powerful "voice" to it than any other knife I've seen and the actual performance on it feels so tight it may as well have been born a fixed blade.
Now, for most people (me included), they have to try and Justify spending upwards of 300-400 dollars on a single knife. I've not really been in the knife collecting arena very long, I started when I was around 16 or so and now I'm a 19 going on 20 University student, but for what it's worth, I've had my hands on some of the major brands so highly touted out there like Benchmade, SOG, Cold Steel, and a number of others I scrimped and saved to buy, but I have to say, despite the incredibly steep price on this rather plain, quiet, and unobtrusive knife I've got now, I'd sell every single other one if only just to keep this Sebenza.
All in all, there's a good reason as to why when you go look online at knife reviews, all roads lead to the Sebenza. It's in a class of it's own when you get right down to it.
