Just because your S30V knife is sharper than your VG10 knife does not mean that it is because of the steel. Blade geometry has a lot more to do with it. Even how long the edge lasts has as much to do with edge retention as steel type. Spyderco is a great company to test different steels because you can often find identical knives in different steels.
This is the whole point of the Mule knives.
I am a big fan of S30V. It is a heck of a good steel and I just had a new S30V knife show up today(Chris Reeve Inyoni) but there are some knives that are better suited to a mid grade stainless like VG-10 or AUS 8. The Yang kitchen knife is a great example of a knife that is better off with VG10 than S30V. It does not need the extra toughness and should be easier to sharpen.
