I thought that the collective B&B wisdom might be able to help me out with a problem. I've got a French frameback with changeable blades and I'm not sure what the best way to hone it is. If I hone it as per normal, it will start to wear down the spine but that will then give me a different angle for when I hone a different blade as they are not all the same size (some are more worn than others). To get a great edge, you need the blade to be at a particular angle on the hone which is determined by the size of the blade and the spine. What happens though when the size of the blade is different?
