Not silver or gold!
These "precious metals" are steel, copper, brass, lead, and aluminum. The steel, copper, brass, and lead are contained in the Glock. They help protect the actual precious metals and they're just as fun in their own way to play with (shoot at the range).
The aluminum is contained in the windlass on the SOFTT-W tourniquet. A tourniquet when properly used helps keep your precious blood in your body if you suffer a traumatic injury resulting in severe hemorrhage.
A slight variation from the norm in #steemsilvergold but I believe the tourniquet pictured and training to use it and other medical gear to be even more important than silver, gold, or guns in daily life and in any kind of collapse.
