If you ever hone a straight razor. It will be good for that.I just ordered a set of Shapton Kuromaku stones. I purchased a 4-stone set of #1000, #5000, #8000, and #12000, to this I added a #2000. I don't know what use I will have for the #12000 but it was cheaper to get this set than the first 3 stones by themselves.
