Excellent set of stones, all in a single self-contained unit complete with oil. I have enjoyed sharpening the kitchen knives for 40 years. This set is by far the best I have ever purchased. I like how the wood holder keeps the stones off your work surface to allow you to easily sharpen the entire length of the blade.
