Get yourself some wet and dry paper in varying grades from coarse to polishing and some hardwood dowel, say just little finger thickness or smaller, you can adapt it to the curve of the knife. Cut a long strip of the wet and dry paper so that it can be stuck around the dowel with waterproof glue. When you have done that you will have a selection of hand made custom hones which will tackle anything from a chipped and damaged blade to polishing the finished blade. Use a stropping stroke ie draw the knife or the hone away from the edge, keep the angle the same as the manufacture's angle, do not try cutting into the paper. Rinse or wipe off the hone from time to time to keep it clean and keen. Treated sensibly these hones will last a long time,can be carried in the field and are cheap to replace if lost. If you merely wish to realign the edge using a steel just use a smooth steel rod as you do not have to remove metal from the edge to do this. Using a coarse steel will sharpen but also degrade the edge so that it will not achieve maximum sharpness and strength for the job in hand and will blunt quicker. Drop me a PM and I can give you a demo if you wish. Bob
