What Benchmade says:
If there is ever a time when you must go alone, the brand-new 430SBK Redoubt will keep you confident and capable. When you're your own first responder, the 430SBK REDOUBT is a solid EDC for utility and self-defense with Grivory handles and a drop-point CPM-D2 blade making this modern workhorse knife a reliable addition to your preparedness kit.

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. The 430SBK also featured a half-serrated edge, so if you are cutting a lot of cord, rope, or line, the serrations could come in rather handy.
