So yesterday I did the stone get and since I was technically always been good I made it right away 3 knives which were previously blunt to get so sharp that you can shave the hair from the arm! And to practice even without pressure from the hair jump downright only so away. So the stone has 5 +++ stars! Men should look before a pair of videos then it works well! But a prerequisite is technical skill! For me there is never a dull blade! Another tip that grinding is not done in 5 minutes, is a lot of work ... but worth it !!! So buy all knives friends, buy, buy and have fun! Oh, and you should still a leather belt with grinding paste can be bought then is it really as sharp as a razor! (Leather straps + paste 10 Euro)
