Hmm. The Covert is a fairly unique item, a folding version of the Applegate-Fairbarn knife.
If something about the aesthetics of the knife work for you, then go for it. If what you are looking for is a folding "fighting knife", there are alternatives, albeit ones with less shapely profiles. Microtech, SOG, and Cold Steel make folders with deeply swedged spines. Microtech are generally regarded as the highest quality, with Cold Steel and SOG being about equal in quality, although variable in cost. There are others if you do some digging.
