Also, it could be the steel of your razor. Some are brittle and they chip easily during the process. In those instances, you need to give the edge some added strength. Most will do that by adding another layer of tape or two to the spine to do that. If none of this addresses your problem, add in some more details about the razor and stones you're using.
