I just used mine about ten minutes ago. Neither my chef nor my santoku would slice mushrooms smoothly. A few passes and they are like new.
Yep. Ran stones and rods for years and never felt the knifes were good.
Now the kitchen knives work even the full one that I could not sharpen no matter what.
Also can use it to sharpen lawn mower blades and the gardening axe. Well worth the money
