I saw a direct comparison of the two steels, modified infi and standard infi, and it seems that the edge holding ability of modified is slightly less than that of the standard.
That, and the handle material seem to be the major differences. Blade design seems identical...until the knives are released, and an objective comparison performed, we probably won't know for sure...
I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world, because they'd never expect it.
