I like the Naniwa Advance stones for razors. Good value IMHO. The binder in the Advance loads up easily, so I always recommend a good amount of slurry on each stone until you get to the finishing stage.
I’ll gladly be corrected by any Honemeister who actually knows what they’re doing😅
I would not use Honemeister and knows what they’re doing to describe myself, but here goes:
Since you have already honed quite a few razors, I’m leaning towards steel temper as the problem. An easy way to tell is to go back to the 1K stone and don’t come off of it until it push-cuts a packing peanut. It should take a little effort and the peanut may make a sound when push-cutting, but the razor should cut. Sample cuts from heel to toe should feel the same. If the razor does not push-cut, then try to inspect the edge with a 25X loupe, or equivalent. The texture of the apex relates to the abrasive size of the stone, but temper issues typically prevent the edge from taking the smooth form that you expect. I suggest using Sharpie, also, just to have a visual check on overall geometry.
If the steel is soft then half strokes on one side of the razor will easily form a burr that you can feel with your fingers. The burr will be on the side of the razor that faced up during the half strokes. With soft steel, this burr is easy to flip (with half strokes) from side to side, and it is very difficult to remove with alternating strokes on the stone. (video go to about the 29 min point)
Hope this helps!

You know, I’ve seen you mention this a time or two and I think noticed it elsewhere but still have yet to try it. Next razor I’m going to try and remember to bring some peanuts around. Usually I just try to get it shaving arm hair to determine if a bevel is set and then I cut an unsupported strand of hair as the final test but this does seem more convenient and might offer better feedback for the stages in between.
I looked to your videos for a bit more detail and found this, thanks: www.youtube.com/watch?v=ieTUQM0YwZA
Also, I’m curious which microscope you use? …nevermind, you answer in a comment here www.youtube.com/watch?v=hmD7UJ6e0II&lc=Ugz6_cFe2R… that it’s this one www.dinolite.us/products/…/am73515mt8a/

That’s why I do it. I like feedback on the sharpening process as it progresses. When I sharpen knives, I do it by feeling the edge for burr and for refinement. I can do this frequently during sharpening, and I’ve done thousands of these, so I have that feel dialed in. A typical razor has half the bevel angle of a thin knife, and my feel isn’t that good. For razors, the polystyrene packing peanut was the answer. It’s a test that is consistent and is easy to do during the sharpening process. I can use it to determine how the edge is progressing on any stone (or slurry) in a sharpening progression. And, it also allows me to check the consistency of keenness along the entire edge.
