Thanks all for the info but is there any videos to show how to sharpen my japanese knives/In the past month I saw a video online of someone sharpening some japanese knives which was way different than the way Iwas used too. My past with sharpening with my Germanknives was using a tri stone and sharpening technique was much different ,which for me I always had a razor sharp edge.Now with these type of knives the sharpening is different and I don't want to mess it up.
