Exactly what I was looking for. As a beginner slicing and slicing, the sharpness of my knives is really important and sharpening knives and getting the right angles is an art form that will affect or detract from the sharpening of your knife, the ease you can carve and the outcome of your work can. Thankfully, this product has taken the guesswork out and made sharpening the more complex curved tools much easier and faster. It has a rubber base on the blocks so they don't slide on you. I will try to get a wet sharpening stone from this seller as soon as my money allows.
