When you sharpen with a stone, whether it be a " Whet" or " Diamond" what is primarily happening is you' re displacing (rolling) the metal to the opposite face of the side being pushed across the stone.
As you flip from side to side, the displacement of the metal forms a " Wire Edge" and until you knock off that " Wire Edge" your knife will forever remain dull.

How do you knock it off?

Have you ever seen a Barber use a whetstone on a straight razor?

Heck NO!

He grabs the end of a Leather strop and with a few passes he' s ready to shave.

Essentially, He' s knocking off the " Wire Edge" before he heads for your throat.

Accusharp' s are fine for Meat Clevers and Hatchets IMHO, but what they do is TEAR the metal away leaving microscopic jagged edges and valleys in the edge.
If you were to look at the edge magnified you' d never use one again.
The resulting tearing leaves bazillions of little teeth (for lack of a better term) just itching to break off in what ever you draw the edge through.
I' ve taken knives sharpened with Accu' s and drew a ceramic rod across the edge and let the owners see all those bazillion little bity specs of metal on the face of the rod.
