I have a few knives, many of which are starting to dull. I want to get them sharp, and from looking around have found that using good quality whetstones and a strop will get the knife as sharp as it can get. Now, I wouldn't need a real course stone, none of my knives are that dull. So I am looking for a two sided stone, medium on one side and then fine on the other. I don't want it to be THAT expensive, but I don't really know the range so I will welcome any suggestions.
