Nice illustrations Gideon, most folks would waste a lot of time trying to type an explaination (I'd be one of them).

My Lansky is a little old, but it has a small lip near the tip of each jaw that works well for me. It's a bit fiddley getting the blade in there, but that's how I sharpened my YKCG and it worked great. Perhaps yours doesn't have that though.

IIRC, the angle I used was 30 degrees.
