What Benchmade says:
Look no further than the 430SBK-02 Redoubt for all-encompassing preparedness from self-defense to hard-use utility. The new under-the-radar, all-black variant of this robust EDC features tough CPM-D2 blade steel with a Black Cerakote finish and durable Black Grivory handles with a highly textured pattern for a sure grip with or without gloves.

CPM-D2 Tool Steel (HRC 60-62)
This powder-metal version of conventional D2 steel benefits greatly from a smaller, more homogeneous carbide structure than its counterpart, resulting in substantial improvements in toughness, wear resistance, and corrosion resistance. 

Grivory
Glass-filled thermoplastic composite known for being extremely light and curable. Widely used for automotive, industrial, and aerospace applications.

Quinn Knives' take:
Most customers notice two things right away with the Redoubt: how light it is, and how much texture the grip has. This hard-use knife clocks in at only 3.1oz so while tough, it is also pretty darn light. In addition, the Grivory handle has some fairly aggressive texturing, so when you require a secure grip, this has it.
