CPM 4V is a high-performance powder metallurgy tool steel developed by Crucible Industries, optimized specifically for toughness and impact resistance. It features a refined CPM microstructure that significantly improves durability compared to conventional tool steels. While its edge retention is good, it is not its strongest feature; instead, it excels in resisting chipping, breaking, and deformation under extreme stress. It is widely regarded as one of the best steels for hard-use survival and outdoor applications where reliability is critical.
