Benchmade Redoubt 431SBK-1 Serrated Folding Knife, CPM-D2 Tanto, Ranger Green

The Benchmade Redoubt 431SBK-1 is a manual folding knife built for hard-use EDC, tactical, and field applications. It features a 3.53-inch CPM-D2 tanto blade with a fully serrated edge and a Cobalt Cerakote finish, delivering strong corrosion resistance and edge retention under demanding conditions. The knife opens and locks via Benchmade’s AXIS lock system, which is ambidextrous and known for its durability and smooth one-handed operation.

The handle is constructed from Ranger Green Grivory scales with a Forest Green textured overlay, providing a secure, lightweight grip in wet or dry conditions. At 3.7 ounces and 8.27 inches overall length, the Redoubt carries easily and deploys reliably when needed.

Benchmade’s LifeSharp program covers this knife for the life of the blade, including factory re-sharpening, cleaning, oiling, and mechanical adjustments at no charge. Hand wash only care is recommended to maintain the finish and edge integrity.
