The Tri-Angle Sharpmaker has good repeatability better than compared these round Abziehstähle. You can reach theoretically with water stones a higher or finer focus, however, is always connected with a lot of effort. I let the Sharpmaker are built, each knife prefer mostly before any prolonged use, a few times about it and have thus a permanent high sharpness. Priced it is compared with Abziehstählen or miracle sharpeners from the grab bag pretty exclusively, compared with several including to watering stones circulation and dressing plate pretty low -> in short:. The price is reasonable the utility. Posted by guests: "Compared with the knives here, are the home like spoons."
