Advantages of D2 over S30V

D2 has a higher toughness, in other words it can take more of an impact before chipping.
 
Neither are very tough, they are probably very similar in most respects at similar hardness levels. D2 is usually ran harder and has a very high wear resistance and thus offers better edge retention, though I would not bet on D2 at 62 HRC out lasting CPM-30V at 62 if you had someone push on it hard like Wilson will do. S30V will have better corrosion resistance generally.

Kershaw has just come out with a knife that is made of D2 and has a ten inch blade. Is D2 a good choice for such a large knife? I thought D2 was considered best for smaller knives (blades under 5 inches).
 
I have used alot of D2 and it is great steel for any lenght. S30V is better. imho S30V is one of the toughest alloys on the planet. The trick to any knife is proper heat treatment, 58-60Rc is just right for both. proper design and use of that knife to match the design. You wouldn't dig a hole with a golf club would ya.

So why would someone pay $30-40 more for the S30V Ritter Griptilian when they can have the D2 Griptilian?

Because some folks like the blade shape and are willing to pay for it. :)

different blade shape (IMHO nicer), full flat grind.

What is the knife to be used for, if it is a fillet blade then yes. D2 has high wear resistance, high hardness, low toughness and low ductility and tends to shatter into fragments when overstressed.

Dante's Knives gives the follow usage description for the Kershaw Outcast:

Tough steel combined with a comfortable shock absorbing handle will make short work of camp tasks, shelter building or blind preparation.

No, wrong steel for that, D2 is optomized for the exact opposite set of properties you want. D2 is a high wear, high hardness steel with low impact toughness, low ductility and low machinability. On that class of blade you want high toughness, high ductility, high machinability. Decent looking blade though.

My 705 is D2.

I love it and it doenst loose an edge fast at all. The steel does chip easy, but its rather hard so it would. I like it.
 
Sure sounds like they are the same except S30V is more corrosion resistant. That would make it seem to clearly be the superior steel? Am I wrong? If so please explain!

The D2 is $80 from Cabelas, the S30V is $105 from areomedix. S30V is better all around. Plus, all the D2 Griptilians are black coated, and some people don't care for it.
 
Whatever the edge hardness on my knives, all of my D2 blades hold their edge at least 2 to 3 times longer than all of my S30V blades. The only steel that I have found that comes close in edge holding is CPM 3V.

I'm done buying S30V. VG10 holds an edge just as long, and sharpens up much nicer, for me, anyways.
