Hi there. So, I've been using a straight razor for roughly six months, and it is now very blunt. I got given a Belgian coticule as a gift (wouldn't have been my first choice as I'm new to honing). I've been playing around with it and so far I'm not getting anywhere. I blunted the razor on a jam jar first (so it no longer shaves arm hair), then proceeded to raise a thick slurry and try some different strokes. No matter what stroke I use, the slurry goes grey very quickly, but the edge gets no sharper - any tips would be welcome.
