True, but he says himself that even his kitchen knives give him a better shave.
If something explicitly designed for shaving gives you a worse shave than something which is not, then it is safe to say that something is really wrong.
I see your point. But don´t you think this observation of a comment he made during a shave with a kitchen knife is too vague to count as evidence?

Lynn did it, with several razors.
It was 'No go' on the shaving comfort.
Now it´s getting interesting. Lynn actually shaved with several Razors honed by Murray Carter (lately and not "out of box" but explicitly sharpened ) ?
