I have kind of gotten into sharpening knives as a hobby.
Here is what I use
only that's a leather strop on the Kalamazoo right now.
I usually start with 220 grit if the knife is extremely dull. I get a lot of knives that way.
I'll go to 400 and 600 and finish it off with green rouge on the leather strop shown in the first picture below.
I can take ten very dull knives and have them shaving sharp in 30 to 40 minutes.
Some of my belts.
Party of my work area where I not only sharpen knives, but do my best at making them purdy again.
I have a little DMT for touching up knives when I'm at my desk.
