I think before u start to master the coticule read planty of comments here about the advantage and disadvantage of this hone...If u use it for finishing, touch up, or somwhere at the range of an 8K hone it's okay, but maybe you need something else, and in this case it's only wasting time...At the early days I had lots of frustration when I wanted to get something from a hone, what I couldn't get:-)
