From Spyderco's website:

Zapp Tooling Alloys’ Z-Wear BQ™ is a “blade-quality” expression of Zapp’s Z-Wear PM® tool steel. Z-Wear PM is a particle metallurgy cold work tool steel created to offer wear resistance superior to standard tool steels with the added benefits of increased toughness and resistance to chipping. The BQ form of this steel further enhances these qualities to provide optimal performance in knife blades and other cutting tools.
