Dynamis Neptune IWB Kit | Corrosion Resistant Concealed Carry Combat Knife

Salt. Sweat. Street Ready.

The Dynamis Neptune IWB Kit is a corrosion resistant concealed carry combat knife built for extreme environments and serious daily carry. Designed by Tier One operators and finished with proprietary NEPT X coating, this double edge fixed blade is engineered to perform in saltwater, high humidity, sweat soaked conditions, and demanding urban environments.

At 8 1/8 inches overall with a 3 1/8 inch spear point blade, the Neptune IWB delivers deep concealment without sacrificing control. The CPMS 110V blade steel offers outstanding edge retention and cutting performance, while the scale grip system locks your hand in place under pressure. Partial serrations increase versatility for rope, webbing, and emergency cutting tasks.

If you are searching for a corrosion resistant concealed carry knife, saltwater safe tactical fixed blade, double edge self defense knife, or IWB combat knife made in the USA, the Dynamis Neptune IWB Kit is built to survive environments that destroy lesser blades.
