Back when Tools For Working Wood had them in stock I bought a Norton set of 1 1/2 hones. I got a 1k, 4k, and 8k. Thanks to Chris L for posting that they existed. I have used them on smiling blades and warped spines with success.
My father taught me to hone pocket knives when I was a kid. He was a carpenter and new his stuff in that area. Years of honing knives with clip blades made the rolling X easier to understand and pick up. I think there is some crossover in the technique. The narrow hones are real good for that although I find I can do the rolling X on a 3" wide hone as well.
