There's a company founded by the Busses and run by Mrs. Busse called Swamp Rat Knife works, and there is even a forum here dedicated to it. They don't use A2, rather they use D2, and SR101, which is a modified high-carbon tool steel But, let me ask you this, is there any reason you don't like INFI or the current Busses? It's said that INFI stronger that A2.
