A fine grit stone is a great tool for pushing the edge a bit further, and a #3000 grit finish gives you similar refinement without sacrificing too much of the edge retention of finer stones. In addition, it is a practical range to have as a touch-up stone for professional cooks and home cooks alike. 

Recommended usage: This is a splash-and-go stone, meaning no soaking prior to usage necessary. It excels at creating a toothy, yet refined feeling edge for almost all types of steels. It feels a bit finer than other #3000 stones and has great sharpening speed. We highly recommend this stone to anyone seriously interested in maintaining a toothy edge on his/her Japanese knives, but we do not recommend this stone for polishing wide bevels as it creates very little slurry on its own, and contrast.
