I just got off the phone with the seller, what a gentleman! He said explained that if I have a narrow hone I could use a different technique to be able to hone it, just like Bart said. But he said if I'm comfortable with it I could just send it back and there is no problem. He would also check if everything is fine with the new razor.

He also said that he did not check the razor the first time because he was so exited to send the razor as soon as he got if from TI. (there was a problem with the ordering at first, but he was kind enough to order the razor directly from TI for me).

Anyway it seems everything will turn out for the good in the end.
But still, we customers must always rely on good and kind sellers rather than having trust in the manufacturer..is that the what we want?
