Review on Efficiently Sharpen Your Knives with the Suehiro CERAX CR 1800 Combination Sharpening Tool by Jose Guevara

I was happy to get decent edges on my German knives. After about 15 minutes of use, the 320 grit on my '57 Rockwell Chef's Knife was burr free. A huge bulge formed in the stone, making it impossible to get a straight edge. There was no metal in the slurry that formed when I was sharpening my knife, it was just white (the color of the stone). The rock is too soft and loamy like there are growths on the rock that are incredibly thick and slippery. An absolute waste of money. Don't you dare buy this junk. This picture showed the stone after only 15 minutes of use on a flat surface.
