Well, don't know if you've found one yet, but I'd suggest a Large Sebenza carried via the clip and the Mnandi on your belt in a small sheath, a good combo I'd say, since you've got the Mnandi already.
I
just received a large wood inlay classic Sebenza and to go along with that is my Case stag handled wharncliff slip joint that I carry in a small sheath, great for those small chores while the large Sebenza can be there for more challenging/larger chores...I've had many many Sebenza's, a Mnandi and an Umfaan, the Umfaan is fairly a smallish knife, too small for me but still a nice knife.
Here is a scan of some of the Sebenza's I owned, these are all gone and there are several missing from this scan, now I'm down to this large classic wood inlay that I just got, she's a little marked up but still a sweet knife, hopefully a keeper!
Now a Wharncliff Umfaan size? GREAT SIGN ME UP!

edited to add the new wood inlay, I THINK it has a BG42 blade, as I took it apart to reverse the screws, makes it look sleeker to me

, and there wasn't an S on the blade's tang...anyone know for sure when the wood inlay's started coming out with S30v blades?
