I could see some value to a lower-end knife based on the Sebbie design as a "beater" knife, something you can subject to hard use or the possibility of loss without wanting to cry when it inevitably breaks or disappears, while still being a solid and reliable piece. The design IS a very robust one, and the fact that it hasn't been ripped off MORE is surprising to me.
Still, I wouldn't touch it if it only has a liner lock and not a frame lock (they refer only to a liner lock, and many consider the frame lock to be a type of liner lock.) I'd also like to have a better steel; 440A is certainly usable but there's much better to be had for comparatively little extra expense. I'd also like to see some design features to better differentiate the knife from the Seb - a different blade or handle shape (a more traditional drop point would be nice esp. given the weaker steel.) Though the part-serrated blade is a nice touch in this regard.
Sebbies, fortunately, are not simply a base design - the materials, craftsmanship, service, and aesthetics are every bit as important, if not moreso. They can imitate the Sebenza all they want, but Sheffield will never even TOUCH the original in any of these areas.
These things also don't hold a candle to the beauty of the Classic Sebs, and no way in hell could they make a knockoff that didn't look/feel like a toy and have any real resilience as far as the inlays go (they'd look like crap, too.)
The Mnandi is still safe though, right? (oh please, let it still be safe.)
