How long before my knives will become razor sharp when using whetstones?
Again, your skill level will dictate how sharp your knives will get. Many of my viewers have expressed after attempting to sharpen on whetstones about a dozen times, they get the hang of it. So, if you practice hand sharpening your knives on whetstones, just once or twice a week, you probably will be able to develop a fairly sharp edge in just a few weeks. Results will vary.
