I'm new to knifes and sharpening, I'm trying to decide what knives I think I need. In the mean time I'd like to order 2 or 3 stones, I think the Naniwa Professional Chosera 1000, 3000 and 5000 is a good start. I'm looking for stones that aren't to soft and cut fast. I think those stones will be fine for sharpening good carbon knifes, I'd also like to sharpen softer knifes on them as well. Thats the part I know nothing about, will it ruin the stone? If it will damage the stones is there a product available that I could sharpen both types of steel with?
