Keeping a waterstone flat is part of regular stone maintenance. Waterstones sharpen very fast because the binder that holds them together breaks down quickly constantly exposing fresh grit. While this results in faster sharpening, it also means that the stone wears relatively quickly and will lose its flatness through continued use. With proper tools and technique, your stone can easily be flattened and provide you with years of quality sharpening.
