I agree with "Rickster", I tried it as soon as I got my umnumzaan and it definately fits. Its a little snugger than my large sebenza, but it definately fits. The only thing that makes it a little snugger is the glass breaker protruding. But if carried regularily in the sheath, the leather would conform around it and loosen it up a bit. I carry my umnumzaan clipped to my front pocket though like my old regular sebbie.
