I too have a Ken Onion, what I have learned is This sharpener is great to sharpen a knife, I have pumice, cermanic, Arkansas hard stones, even diamond stones & strops too. The Onion Sharpener saves me a solid week of sore arms from sharpening manually the the new knife for the first time to achieve the angle I want on a blade. BUT the best thing for a knife is a steel.
Once you achieve a good angle on your blades edge, just constantly when using it, hit it a few times with that steel. it takes that burr off the blade.
Now a days I do have some nice knives, but its the steel that keeps them in the game. I sharpen mine usually once maybe twice a year if a lot of processing. Its the steel that allows that to work that way.
Look for you a steel, they are worth the cost.
