Something we can all relate to
"Volkov and Kononenko (see pic) needed six hours and 18 minutes to tackle the suspect bolt "
I had one like that once, under the sink.
Cosmonauts Oleg Kononenko and Sergei Volkov yesterday ventured outside the International Space Station to remove an explosive bolt from the Soyuz TMA-12 spacecraft amid suspicions that faulty pyro fittings may have been responsible for two ballistic re-entries into Earth's atmosphere.

What is a "blast-proof" case? Perhaps they meant something more like "blast-containing", but even that wouldn't be completely accurate since it obviously could only handle a blast up to a maximum energy output. My guess is it wasn't a perfect translation. Nothing is "blast-proof". Anything can be blasted/destroyed with sufficient energy.
I'm sure the nerds on the ground designed the case to contain the energy from one explosive bolt. It's not like they don't know exactly how much explosives are contained within one of the bolts.
Plus, as an explosive bolt, it has enough power to instantly sever the bolt (with a decent safety margin), but you are not talking about something designed to "open" armored vehicles.
