You already know how to sharpen. Those same techniques you use to produce a flat or bevel edge will produce a convex edge if you change to a leather strop on wood with compound (of course you must not use the edge leading on that). If your technigue has worked on other knives, it will work on any Busse made knife. Consider yourself skilled. Some folks can't sharpen at all. As for a Scandi grind, that is the easiest of all to sharpen. You just sharpen at the same angle as the bevel that is already there. If you use a stone, it will be flat, a strop it will be convex.
