It took me years to get good at sharpening. The most important item was raising my expectation of what is sharp. I consider cutting hair to be an indication that that the knife is just beginning to be sharp. I now finish on one of these: extrafine diamond stone, 2000 grit wet or dry sandpaper on glass or granite, or 4000 grit water stone. Then I use chromium oxide on leather strop. It produces a mirror finish and you can see yourself on the steel.
If you check it on soft pine it should cut sapwood and heartwood cleanly with no tearing. It should also slice a piece of paper held in the air with no tearing.
As a place to start the "Scary Sharp" movement to use sandpaper to sharpen works really well and does not take alot of money to start. If you google "scary sharp" there is lots of information.
I had to quit sharpening my pocket knife like this. I was getting too many cuts opening and closing it in my pocket.
