If you haven't tried this diamond stone, you have a pleasant surprise ahead. This practical and lightweight sharpener is incredibly good for sharpening all kinds of cutting tools due to its ease of use. The diamonds offer a really fast sharpening experience on any steel you test it on. Additionally, it doesn't require oil or water, and if you think the DF24 feels smooth, wash it with warm water and detergent. At first, the diamond stone may feel a bit rough, but after a brief settling period, it provides a very smooth and sharp edge, good enough for almost any use. The diamonds are fixed to the matrix with a layer of titanium and aluminum nitride, which greatly extends the lifespan of the sharpening stone.
