I don’t find VG-10 as used by spyderco or anyone else at typical hardness to be any more difficult to sharpen than 440c, N690, or sandvic 12c27. The thin behind the edge flat grinds spyderco tends to use are a breeze to touch up, though some of the saber grind models are harder and end up with a wide bevel at my preferred low angles.
A Norton India (alum ox) works perfectly well on VG-10, as does the Crystolon Pike (I think that’s SiC), both are cheap and available. Basically anything more than novaculite sharpens VG-10 well for me.
Ceramic stick, and a work sharp field sharpener do the bulk of my edge work these days, but kitchen knives and larger knives warrant breaking out the India oil stone.
The steel works well and is easy to maintain so I like it as well.
