When evaluating distributors, prioritize knives using high-performance blade steels such as CPM-S30V, CTS-XHP, or D2 tool steel for superior edge retention and corrosion resistance. The handle construction should feature Grade 5 Titanium (6Al4V) or high-pressure fiberglass laminates like G10 to ensure a secure grip and structural integrity under extreme conditions. Ensure the heat treatment process is documented, as this determines the final Rockwell hardness (HRC), typically aimed at 58-60 HRC for tactical applications.
