A9(AISI) - Air hardening, cold work tool steel. Apparently combines some properties of hot work steels like AISI H13 and shock resistant steels like AISI A2. What's interesting from knife use perspective, its toughness. Based on alloying components, it's more wear resistant than AISI S7 which makes pretty good heavy duty knife steel.
