I like thin so on skinners I go to .010" hunters usually .015" and then on choppers and camp knives.020-.030" it all depends on the use of the knife, and to some extent the steel used, the same with sharpening angles, my thin skinners get around 17 degrees, hunters and utilitys get 20 degrees and choppers 22 degrees to raise the burr, then increase the angle by 2 degrees to remove the burr, this gives micro bevel backed up by a primary bevel for edge strength, any of the above angles will get hair popping sharp. This is the method that was taught to me buy a professional knife sharpener, and has done well for me.
