Pros: Durability, Ease of Use, Effectiveness, Overall Quality
This is what a silicone oxide stone should be.
Been sharpening knives with bench stones for 15 years. The first step when working with a worn out knife is to have a stone that can cut fast. This is definitely one of the best silicone oxide stone I've used. Other brands I've used does not grab consistently and slip, leaving ugly scratches on the side of the blade. This stone, however, grabs like dry sand paper and gives an even, consistent edge.
