This stone is fantastic for sharpening my blades back to their factory edge. It has an ultra-fast grinding effect and the stone itself is extremely low wear. This stone is suitable for all types of knives EXCEPT for ceramics. Though there is certainly a learning curve, these stones are for sure the way to go, especially for high-quality knives such as Miyabi knives, Kramer knives, and Zwilling's. But, like the any other stone, you still need a lower grit to sharpen and you finish with the 1000. I would recommend that you practice with a cheaper knife if possible, just to make sure you get a feel for the motions and the process. But the perfect edge really makes for effortless cutting and elevates the cooking experience.
