The outside of the blade has a convex surface from the tip to heel as well as from the edge to the spine which means that there is a complexity to could lead to headaches if you get it wrong. Regular stropping however on the inside edge using a dowel with stropping compound and a stropping paddle for the outside edge is a great way to maintain a keen edge for longer before you will even need to think about resharpening your hook knives.
