Thermite, door entry, life post SHTF

[Sunna]

I never done this sort of thing honest .

safe ....drop it out of a high building its own weight will break it open...
even with a claw hammer given time or drive a fork lift at it forks put together always works.

strong room ...same given time you will get in .

most security is based around someone seeing you or hearing you , if tshtf no old bill coming ...so relax plenty of big tools for the job.
