On VG10, some wet/dry sandpaper (silicon carbide or aluminum oxide) in the 320-800 grit range will leave varying degrees of a satin finish. 320-grit, or sometimes even 220, will emulate a lot of factory satin finishes. Wrapping a piece of sandpaper around a rubber eraser makes a decent sanding 'block' which more evenly distributes pressure (makes a more even finish) and will conform to contours of the blade more easily.
You could also rub them down with a ScotchBrite pad, such as the green ones commonly found at the grocery store for kitchen/bath/sink cleaning duty. It'll work a bit more slowly than the wet/dry sandpaper, on hardened cutlery steels.
If using the sandpaper, you might start with a higher grit (maybe 600) and see what that looks like. It's better than starting too low and then having the too-coarse scratches left to clean up, if you don't like it that coarse.
