Pros: Durability, Ease of Use, Effectiveness, Overall Quality
Great Stone, does it all.
This is my go to stone for all sharpening: kitchen/chef's knives, boning knives, sport and carry knives. It cuts, quickly, doesn't load with metal and is easy to clean, and gives a really sharp edge. I own a retail meat shop (and shave with a straight razor) so I can confidently say that unless a knife is badly damaged (in which case use a machine) or your sharpening a razor (a finer stone would be better) this is all you need for hand sharpening. Thick heavy stone is very stable during use.
