CPM Rex 45: CPM Rex 45 (similar to Hitachi HAP40) is a super-high-speed, particle metallurgy tool steel similar to CPM-M4. Higher levels of cobalt and tungsten allow for higher hardness and better strength, improving edge stability for thinner, high-performance edges.

A true steel connoisseur’s blade material, REX 45 is an ideal steel for this prestigious Manix 2 Sprint Run produced in our USA factory. To further distinguish this unique steel, all REX-45-bladed models feature a distinctive burnt-orange handle color.

CPM REX45's high cobalt content increases its attainable hardness, while its vanadium carbides provide high wear resistance, fine grain size, and increased toughness. This knife’s blade is further distinguished by a black Diamond-Like Carbon (DLC) coating.
