The original NSK Kogyo diamond stone series, Kyokuha are built for ease of use and compatibility with a wide variety of steels from carbon, stainless, powder, even tool steel. It has a large selection of grits to fit almost every user's needs. These are the softest of the NSK series and probably easiest to learn sharpening and polishing. I
