Ok this is all bringing back memories again. I just re-honed this and tried to shave and i remember i have been through this experience before: It seems to start off sharpish then after about half my face was shaved it becomes very pingy and basically feels rough and doesn't really cut well anymore. I continue more and it gets very uncomfortable and seems to start pulling. My questions:

1. Could an edge deteriorate this quickly?
2. Could this mean i just can't hone thing blade to save my life?
