Is it possible to use an ordinary whetstone? Will not damage the tool?
Dear, don't be silly, I'm a living example, ah, the Zwilling tool I used before is the ordinary grindstone to wear, now I have heartache!
Right, there is a special knife sharpener, or sharpened periodically better, if LZ do it yourself, ordinary grindstone, collocation Zwilling tool is not very good, may also damage the blade, anyway, my family is a special. If LZ does not want to spend money or too lazy to do it, you can go to the counter. Remember, oh, it's free and permanent!
Zwilling is as good as cattle ah, even the sharpener is dedicated!
