A couple of thoughts to add now that I have a chance.
I don't really ever try to keep steady angles. I start out thinning until I get a burr. By thinning I mean that my angle is pretty much as flat as it can be for that knife. Then I gradually move my finger pressure down closer to the edge, alternating back and forth. Raising a burr, flipping (technically switching) the knife. Until I'm focused right on the edge. As I move closer to the edge I do steadily diminishing pressure as well. The result is a slightly convex zero grind. Then I add a micro bevel appropriate for the knife. That could be just on one side, both sides symmetrical, both sides assymetrical, flat or convex or blended into the original grind or whatever. And then after that I add my nano bevel. That's what I call the result of the high angle pass. It's usually about a 75-90 degree inclusive micro micro bevel. I don't get rid of it like he does in the video either. That's my working Apex. I will strop it a little. Just a few strokes on my hand or newspaper or a stretched kitchen rag.
The Science of Sharp guy says that the way this works is a high angle pass, even with a feather touch puts an extreme amount of pressure on the edge because you are impacting such a small surface area. This results in a lot of plastic deformation. The guy in the video demonstrates the high angle pass part pretty well. That's the only reason I shared it.
You don't have to go so extreme to see the benefit.
I started just going a few degrees above my main micro bevel, but since I've started playing with straight razors my feather touch game has seen big improvements. I've been testing this on everything I have. Shirogami, VG10, Aebl, 52100, Super Aogami, 1095, W2, O2. No exotic stuff. You end up with a nice sharp sturdy working edge. For medium coarseness. I don't think this strategy is necessary if you are Finishing on actual finishing stones. But it's a good way to deal with deburring when you aren't planning on sharpening to 8000+ grit or using JNats or whatever. But always edge leading for all of it.
