I've obtained two almost unused razors- After marking the edge and the spine I lapped each on the DMT 8k. The markings came off unevenly on the spine and the edge of both. Is the next step grinding down the edge and spine until the markings come off evenly? I have a Norton 1K to use for this purpose.
My guess is that after the spine and the blade edge evens out, then the bevel is easily set on the DMT 8k and honed to shave ready on the same steel.
