Best bet is to take a photo and post it. For bad chips I used to breadknife but a couple of times doing that convinced me to never do it again. If it is a bad one I might tape the spine and do a lot of circles. If it is really bad I might hold the spine off of the hone and do x strokes and circles. Once the chip is out go to normal bevel setting and sharpening. One consideration is whether the finished blade is going to be worth the time and labor when your done. Post a photo so people can tell you if it is too far gone to bother with.
