Case, Buck, and a few others usually come with a decent edge. BRKT and Fallknivens come with scary sharp convex edges. Most Cold Steels come with a good edge. My DMLE came with a pretty good edge. But they all eventually get dull. Learning how to sharpen them is best, but some companies offer sharpening service. I occasionally sharpen knives for others. Usually they are heavy duty combat knives that don't come from the factory with a good well finished edge.
