I asked about the knife because UX-10's are a little thick at the edge and pretty solid 70/30 (almost 80/20) grind which makes them on the border line of not a great idea to do this to.
The thing is that what's important to note is that the blade, not just the edge bevel, is ground asymmetrically so by changing the edge bevel you serve to change the way the knife cuts more than anything. I have this info because I do a tremendous amount of re-conversions every year. So you have a knife that starts out OK then starts to twist and bind more and more with every sharpening. Eventually you need to thin major-ly from the inside to correct this problem.
Now if the knife was thin and 60/40 then you can pretty much do anything to it and it'll still cut well. It's the thicker more asymmetric knives that will bring you problems when messing with the edge ratios.
