First, post some photos of the razor and edge.

Look straight down on the edge with magnification. If you see any shiny reflections, that is where the bevels are not meeting. It could be that it was honed properly, but improper stropping could have rolled the edge. “I also stropped the crap out of it on a suede then leather, with chromium oxide”, Dollars to Doughnuts, you have a shiny bevel and rolled edge.
It happens all the time. Stropping a razor takes time to learn, about a year for most folks.

Make sure your “Razor Honer” shaves with a straight razor, not the local knife guy down the street that sharpens lawnmower blades and knives on a belt sander.

Or as said heat treat or bevel angle. Post pics and look at the edge.
