I thought these were rubbish until I went to a food show where they were demonstrating them and realised I was using them wrong. I use them on cheap knives to expensive Japanese Kyu knives. They come out like razor blades after. I don't care if the angle is wrong. What is important is that they make the knife ultra sharp. It's far easier than the wet stones I bought.
It’s because it doesn’t work! At least my knives didn’t get to sharpen at all.
I don't know much about sharpening knives and the comments really confuse me. Why are people saying it's rubbish, when it's just a sharpener that can sharpen your knife?
As asked, you got a link there please?
Oh it does!!
