I never had rust on my VG10 blades though two of them seem to discolor close to the edge, well but my knife care made even a Puma White Hunter rust near the Kraton handle and Gerber Evos get brown at the blade etching as soon as I have them in my pocket. Even some spots on S30V seemed more orange but vanished after wiping off the blade.
VG10 definitely is an upper class all around steel, great EDC, but when it comes to hard/extended cutting my choice is between S30V and D2. Those steels are said to rather chip than roll so it seems agressive edges are more to my liking. I might be a steel snob or a terrible sharpener but the only of my knives in VG10 that holds a great edge over time is a Santoku without any bevel and ridiculously thin. The knife I carry the most is of some exotic steel, by the way: a Robin in 8Cr13MoV. This particular blade hasn't rusted yet but the liners in its handle did.
So it seems I did another test with my Salt1. I still have to find it
