I had previously been a Japanese Wasserstein (400/1000), which, however, quickly wore itself. This set, however, is to make a suitable super coarse grinding and then an acceptable fine-tuning. A 3000 stone would be recommended, but it is possible also to remove the burr well with the super abrasive paste. Conclusion: For ordinary Knife ideal - for more exclusive knife, I would still finer stone (3000 - 5000) to buy.
