Sharpening a knife and sharpening a razor are two different skills. Some people who are great at knife sharpening, never get the concept of sharpening razors. I was never good at sharpening a knife (which was quite an embarrassment because I worked at a paper mill for many years where sharp knives were the tool of the trade). However, I can put a nice edge on a razor. Others have the skill to do both. If you have a good set of hones, you are ahead of the game.
