Not all metal backups are made equally. If you use metal to not have to also worry about your bitcoins when your house is on fire, don't use this product:

But running these tests must have been great fun, right @Jameson Lopp?

If we add these backup solutions to our website, we would certainly heavily lean on Jameson Lopp's work as a hydrolic press and acids isn't what we had planned to play around with ourselves for now.

Jameson are you planning to test more products any soon? Adding "backup tools" to WalletScrutiny might get excessive if we don't draw lines like you did. If it's not at least claiming to be heat resistant, we won't bother to list it or else we end up listing a million different ways to print on paper. 

 I'm pretty much done stress testing backups unless someone comes up with a unique design. 

 The designs look repetitive but the chosen materials appear to not always be clearly advertised. Maybe educated guesses are good enough if people ask about any particular new device.
