Thread: Slurry Dulling

+1 big time. I find I max out sharpness at a much higher level on only water. When slurry is then applied the edge dulls due to impact with the hard garnets. Not a coti expert but have had a few. If you don't believe in slurry dulling try taking a shave ready edge to a coticule with slurry. The shave is "slurry dulled" to say the least.
