I'd definetely call Kershaw. Blade chipping is almost always a sign of improper heat treating....the blade is too hard and brittle. Depending on how much they raised the Rockwell on it to achieve that poor heat treat, I"ve no idea what steel they are using, a diamond hone might be called for, but I certainly wouldn't waste good money on trying to sharpen an improperly processed blade. Kershaw has a pretty good reputation for customer service, so I suspect they might help you here. Can't guarantee that of course.
