Micro bevel, looses edge

I’ve been following this micro bevel vid by clay and its been working for me. He was using a 200 grit which gives a nice toothy edge for some of my kitchen knives.

I have two large thin Japanese chefs knives. One with a fine 1000 grit micro bevel that I use for slicing and the other with a 200 grit micro bevel that I use for cutting.
