Keep in mind if you used something like a belt sander to sharpen you can wreck the temper in the edge and make it more prone to problems. This goes for any blade. The second thing, I remember some Busse blades use to have issues with micro chipping until you sharpened away the factory edge, then you ended up with the peak performance.
Not sure about your case, however I will echo other sentiments here, steel it & touch it up but don't sharpen it right out. Keep enjoying beating on it and you will eventually sharpen them out through your regular touch ups.
I've still got a couple marks in my DF edge that I should post up here. I was chopping up a computer case and hit a couple of spot welds. Needless to say, the spot welds won, however the DF held up like you would expect it to! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /><img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
