If you ever want to master freehand get some Shapton Stones. They cut better than any stone available. They are what I consider a high tech Japanese Water stone, but they are splash and go, no soaking required and they don't clog and I much prefer them over diamond stones. I sharpen very acute angle Japanese Chef knives and prefer Hitachi White number 2, which is one of the purest, finest grained steels in existence with virtually no sulphur or other impurities in it. Of course this all a matter of taste. I also like the Naniwa Chosera water stones. The only thing about a Japanese knife is that if you are breaking down a carcass, ie: boning a hog shoulder, you must be careful when using a Japanese knife and never chop on bone, but go through joints and carefully remove meat from bone. I love Japanese knives, but you must get used to the fact that they have special knives for special purposes. Western knives can be considered more general purpose and more forgiving, because their edges are not as acute.
