I've been uging it for years and it still works well
5 Stars
I've been uging it for years and it still works well
I like that it is set up for either Asian or Euro/Amer for the coarse sharpen and, being left handed, that it works equally well for lefties and righties.The updated version, now lists 15 degrees and 20 degrees instead of Asian and Euro/Amer. 15 = Asian and 20 degrees = Euro/Amer (See photos). Under the current listing, the first video shows just pulling the knife towards you and the second video shows pushing and pulling. I've always used the push/pull method, but, since the first video is from the manufacturer, I plan on trying the pull method instead.One last piece of information. I still finish off my sharpening process with a diamond carbon steel sharpening rod that is also available on Amazon.
