I sighed at your description of how your hard work hasn’t brought forth an edge. Not your fault at all! It’s the pundits of these ridiculous stones in their thousands of grit.
For hundreds of years and as is still the case the people who have made all the furniture you see only ever sharpened to about 400 on a combination stone, maybe if they needed to they would strop a bit as well. As a commercial bespoke furniture maker that’s all I have ever done, and
@Jacob and
@Amplidyne say the same.
It really is quite simple and inexpensive, a Norton India combination stone will cost about £40? Plus a little thin oil. Put the sloping edge of the blade on the oiled stone and then lift it a fraction till the oil squeezes out then rub up and down at that same angle with medium downward force, after 10? rubs up and down feel the back edge and you should feel a roughness at the edge, this is the wire edge, to remove that put the back of the blade flat onto the stone and rub up and down just a few time with pressure keeping the blade flat on the stone, the wire will either have dropped off or is ready to, once it has gone that’s about it, I then have a habit of stropping it on my jeans but probably not needed tbh.
We are only cutting wood. It’s not Rocket science and as I’ve described will be quite sharp enough.
A picture to prove my point and credentials.
