Sometimes copper is your best friend
Marine Special Operations Team (MSOT) 8222 was deployed to Bala Murghab in 2009-10. The team was tasked with partnering with national Afghan forces to train them to stabilize a remote valley in northwestern Afghanistan.
This specialized beryllium copper knife was used by the team breacher to cut plastic explosives.
Currently on exhibit at the National Museum of the Marine Corps
This knife cut every charge used by MSOT-8222 during this deployment.
It’s a Strider BD Beryllium Copper (CuBe). These knives, made in St. Paul, MN, have a 6.5-inch blade, paracord wrapped handle, and go an impressive 0.25-inches wide. They run four-figures but are guaranteed non-sparking & non-magnetic.
They are extremely corrosion resistant and doesn’t spark like a steel blade would. Precisely the type of knife you’d want if your job involved cutting through hundreds of blocks of high explosives.
