All will depend on the maker. If the knife has got a stone sharpening I will certainly try it. But that's rare with the knives I have to deal with. Remember Japanese knives used to come without an edge, as the final user was supposed to put his own on it, or have it done by the retailer. Nowadays they do come with an edge, made by a few strokes and a lot of buffing. Factory edges are rarely worth any special veneration. Some are made to make the job easier: sharpened at very low angles, far beyond what the steel can hold when in contact with the board. This is by far preferable, as with only a few strokes you may adapt it. Other ones are very conservative, with perhaps even microbevels on both sides: all to avoid returns by careless users. No fun to have these microbevels removed. Anyway, in by far the most cases the edges are weak by excessive buffing with the resulting fatigued steel and best be entirely removed. That's why I use a good coarse stone to start with, SG320 or 220.
