Welcome to SRP, and congrats on your advances. It sounds like you have learned a lot already.

As you probably know, barber's hones were made so that barbers could quickly rehone an edge when it started to go south, perhaps inbetween customers when his shop was full of customers.

It is unusual to shave off a 6k edge. Without knowing your barbers hone, my guess is that it is finer than that. I'd propose giving it 5-6 light strokes, changes are it would improve your experience.

Best of luck, and let us know how it goes.
