good stone, with possibly a little faster wear

Icb am very pleased with this stone. The grain is given by German measure (there is also an American and a Japanese measure). The only downside might be that I have the impression that the 400-page itself erodes slightly faster than I know it from other stones. At least can be found in grinding with the 400-grit my personal preference for something more removed material in the grinding water as I know it from other stones the same or lower grain. The stock removal of the 1000-page is normally low.

The stone is a great way to sharpen knives normal cars. Dull knives can be missed with the 400-grit and a good pre-sanding with 1000-grit to reach a degree of severity, which is sufficient for ordinary kitchen knife and for the average person in any case. If you want to have razor-sharp blades (which you can actually shave hair - if only to test how sharp the knife is), you need in any case after the 1000 treatment again significantly higher grits.

For knives which have not been honed for many years and are extremely stump or even have notches, should first 200 (German degree) are pre-sanded with a grit stone, as the 400-grit for this is already too fine.

The stone is ready to come in a wooden box, where you can also grind properly. The extent to which the long-term timber being damaged by the water, but I do not know.

Overall I would recommend the very stone. On the web, there are beyond good video tutorials for knife sharpening.

4 of 5 stars because I have the impression that the page with the 400-grit wears out faster than other stones, with whom I have worked so far. "Fast" can be seen here relatively! You can tell this is not the stone itself, but the abrasive water that reveals more material abrasion than I initially expected.
