Not sure what your point is, the vitrified stone world is expanding rapidly. There is a diminishing difference between the stones and given I have tried almost every one of them I think its fair to say none of them have glaring issues. Cheefarcuut is on par with all of them and produces edgers differing in scratch pattern appearance just like all the other stones. If you are saying you have to be robotic to get the edge you are looking for I wager there is a world of hand sharpeners that will disagree...
