If you're up for another CRK, definitely consider the Mnandi. The small Sebenza's blade is just at 3" and although the Mnandi's is 2.75" the whole knife is slimmer and more of a gentleman's knife to look at, rather than a worker. Despite its looks, it is a very strong knife and it can cut.
If you'd like to try something a little less expensive, look at the Benchmade Big Spender, 2.5" blade and a big clip to serve as a money clip. Very slim, and highly polished stainless steel handle. Looking very different but of similar utility and good looks, the Spyderco Stainless Steel Cricket. Both of these, like the CRKs, are framelocks.
