I haven't seen any testing on Olamic damascus, but my sense is that damascus these days is mostly for looks. The vanadium that Olamic puts into its damascus would help with grain refinement and general toughness and edge wear. But lots of steels will do better in almost any single performance category. Olamic runs its damascus at 57-58 Rc, which is a little soft, but should help with toughness (resistance to chipping and breaking).
If you like the looks and you have the money, buy it. Olamic makes a good knife. But if you're looking for a high-performance blade, regardless of the type of performance you're after, you could do better.
