Hi, hopefully this is the right category. I just got me self a pair of wusthof classic ikon. Now i'm thinking of getting a sharpening stone so I can give them the love they deserve and serve me for many years to come. However, I'm not sure what to get. I'm looking at wusthofs own stones, trying to figure out if 1000/3000 or 400/2000 is the better one to get. Help please?
