Benchmade Redoubt 430BK02 Folding Knife

The CPM-D2 knife is made from a high-quality tool steel that has been used since World War II. It is a semi-stainless steel that offers excellent corrosion resistance and edge retention. However, the CPM-D2 goes a step further by being cleaner, having a more refined grain structure, and providing significantly improved strength and toughness compared to regular D2 steel.
