From the little research I have done S30V is one of the better steels you see in common production knives (Spyderco comes to mind).
That said I'm interested in the Buck Hartsook as it is the least costly option in S30V.
But buyer beware there are some close copies out there, with all the markings of the real thing.
I don't really know if the Buck Smidgen is that bad. It is 420HC steel which is at the bottom of the scale. I don't know if it is much better than the Chinese mystery steel (maybe it is).
