I bought this dual-sided water sharpening stone because all my various sharpening stones are out-of-the-country and not accessible to me; I needed a minimalist and simple solution for sharpening kitchen and utility knives better than the typical kitchen store gizmos. This set absolutely met my expectations, at what seems like a very reasonable price - it allows me to take pride in the sharpening process.
I didn't want to ruin my favorite Santoku knife, so I practiced with my old kitchen knives first. Now all of my knives are very sharp like brand new! It takes practice but works amazingly well!
Nicely made, but I have yet to master it. Practice, practice, practice…. The supporting jig helps a lot. In all honesty, the knives stay sharp and haven’t needed more then a simple touch up.
