May I suggest the Sticky in this forum by Mr. Joe Talmadge.

Mr. Talmadge will share learning to sharpen freehand is a great idea.
Furthermore Mr. Talmadge will share how for different tasks such as cutting rope a more "toothy" is preferable over a polished edge for other applications.
Steel types and angles are shared as well.
Do note, many of the Tests Knife makers use are more for showing the skill of the maker's ability to sharpen such to do varies test.
This does not mean the degree of angles, or finished out is the best edge for everyday uses - everyday uses vary for each individual.
I sharpen freehand. My steel of choice is 1095 or Chrome Vanadium. Hone of choice is Norton , and most times I sharpen using emery paper on a piece of cardboard. Stropping is done on cardboard most times or whatever belt I am wearing.
I often on purpose do NOT want a high polished edge. This edge still passes my "fingernail test" and will shave hair - not concerned about shaving hair. Testing my fingernail is to assure me the edge is complete along the whole blade.
I use this edge to cut rope, garden hoses, slice tomatoes , cut meat, break down boxes to whittle, make a slingshot...general purpose if you will.
Now on a Swiss Army Classic I have, this steel , for me, I do get a polished edge using fine grit and stropping in cardboard [ I do not use compounds when I strop btw]
I can cut a a piece of raw meat - and this edge will slice like a razor blade - it takes a bit of time to draw blood.
Tool for task applies to sharpening. There is not a one-size fits all.
