Your comment is quite naive to put it nicely.
Jon has very specific and direct knowledge of Yoshihiro knives. At the time of his comments he was selling them. He can always be depended on to give a very frank and unvarnished assessment of the products he sells. Jon's opinions have never been shown to be anything less than honest and unbiased. If anything, his reputation is as a guy who bends over backwards to be honest and unbiased. Frankly, he's a guy who generally shies away from speaking negatively about other vendors and their products, and certainly doesn't make personal attacks on other members.
The was nothing negative about his over a year old comments. He said they came with an ok edge, and a less than ok edge. They're Japanese knives, and this is common. Meh.
i'm of firm belief that if you cant sharpen yourself or have the means to get it sharpened by someone who can on a regular basis, you really shouldn't be getting any knives nicer than a victorinox.
