I own a 1k, 3k, 8k and 12k Naniwa SS and coarse up to extra extra fine DMT plates (that I use mainly for knives, lapping and sometimes bevel setting or bread knifing to take a chip out of the edge)... I had no major problems with honing straight razors usually, not that I think of myself as a guru of honing but I managed.. that is until so far.

Lately I can't seem to hone a razor,.. it started that I couldn't get an edge on cleaned, damaged blades (so i thought ok, the blade must be unhonable), than I couldn't get a shave ready edge on a blade I honed before with no problems (eg Dovo Flowing)..
This is driving me crazy and I can't seem to figure out where the problem lies. I set the bevel, (at the last try tonight I achieved the hair popping bevel with the DMT coarse, but it just went downwards as I moved up to the finer grits on Naniwas, ending up with a ...well nothing. I thought it might me the pressure, the lack of it, the shortage of time honing... I can clearly set the bevel (even painted the edge) but can't seem to get these razors to shave ready.

I cleanes the stones with nagura stone and washed them with the distilled water if that might help, although there is probably just sth wrong with my technique...

Any ideas what I might be doing wrong, because I am starting to hit a wall here. Is there any chance that the stones might get filled, clogged with something and not eating the steel as they should?
