Well you take a linen stropping belt. And load it with abrasive , preferably CBN or Poly Diamond. Then use it as a stropping belt , but as a regular progression. All the way from low grit/shaping/repairs all the way back up to polishing and finishing. With 4 or 5 different compounds you can accomplish a lot.
Now in regards to the compounds , I recommend going with CBN , its fast , consistent , and will cut any steel on the market.
Heres where things get interesting. You buy a linen belt and the bottle of CBN and the initial cost is pretty decent per a single grit. But the cost per knife is very low , much lower than any other belt on the market. The only person I know of who has used a decent amount of a bottle of CBN uses a 1x42 , and he used 1/5 of a 2oz bottle to do over 500 knives! You need to keep these clean , and separate from each other in order to prevent cross contamination , but its an excellent system and the most cost efficient way of doing things.
Heres a video showing how to load the linen belt.

A good starting point would be 80u , 30u , 9u , 4u and 2u CBN. Will handle repairs and exceed the factory belts by a wide margin. But you can get products as low as 300u and as fine as 0.025u
I'd also recommend the 1x18 attachment for the WSKO , its the beens knees and will play very nicely with the setup mentioned above
