I believe using any rod with VG-10 is the surest way to create a wire edge.
Speaking of which, I still haven't solved the wire edge problem with my Shun, but have not given up. Now at least I can make that wire wicked sharp, just about hanging-hair sharp, but it only stays that way if you do nothing but fell single hairs with it.
