VG-10 for me. Having owned a Fallkniven A1 previously, and a Mcusta folder currently, I really liked the toughness and edge retention.

Horn Dog, I read somewhere that maybe Hitachi, or one of the other japanese steel makers produces the VG series of steels. They are ranked according to grades...ie; VG-10 being the highest and down to VG-1 being a lower, thus cheaper grade. Don't qoute me on this, but I too was curious about VG-1 and this was a response I got off BF or somewhere.
