I have tried any number of ‘easy’ knife sharpening methods, from ones you draw the knife through, to standing sticks of abrasive, to spinning table models.
In actual fact nothing works as well, or holds an edge as long, as a quality steel blade that has been manually sharpened and manually stropped.
Even crappy dollar-store knives will respond (link).
The problem I have is keeping the angle exactly the same for both sides of the blade, and maintaining that angle throughout the process. I got a a fantastic edge on my 8” chef knife but noticed after I’d finished that my thumb and middle finger were bleeding and the nails had all been ground down to the quick. Ouch. Like a paper cut but worse.
You can’t hold anything under the blade to relieve your thumb or it will be ground off just like the blade (or fingers)., or damage the stone. I propose a wedge at the desired angle that has a roller at the base. When the blade is pushed or drawn over the stone the roller will not be ground off and the blade will be kept at the correct angle.
This could be a very inexpensive item that comes with your sharpening stone. If you are a sharpening nut like me you will appreciate the Shapton stones: 1000, 1500, 2000, 5000. (You only really need the 1000 and the strop for non-OCD sharpeners.)
Bad results from other methods. Manually is best.

To afford another degree of freedom while maintaining the exact angle the ‘rollers’ could be a double line of caged bearings that allow sideways movement. |

I wish I could draw this one for you… |

Of course. There are pyramids all over the planet with stacks of dull blades inside. |

Widely known to exist. <link> shows 10 different commercially available examples. |

It doesn’t attach to anything. It could be given a bit of tackiness with something on the blade side but it’s not necessary. |

The pocket version is about the size of half a credit card and only thick enough at the base end to establish the angle. For long deli slicers a longer unit is available. Same concept: rolling wedge exposing the blade’s edge. |

Some of the examples shown in the link could require a trailer and OSHA certification. The drawback to the ones linked are they all make full contact with the stone, smearing the lubrication away from the edge. The Wusthof has a non-skid upper and a silicone bottom but it still makes full contact. Good ideas; I’ll use them on mine. |

Could you build one out of Lego, with a little Lego slopey bit to hold the blade against, and running on little Lego wheels so the lubrication didn't get smeared off? Maybe I'll try this... |

Some of the ones linked have wheels that run along the table, straddling but not contacting the stone. |

Wheels. Try and go sideways on wheels, with that cool finesse the guy in the sharpening video shows. |
