With seedhammer you can easily store the descriptor in steel. Really great to hear you checked this out! If you need a seedhammer to try and you’re in the Netherlands, let me know.

I'm sorry. In in London. But I would love to see what you mean. The descriptor is like 4 lines long and not really human readable, so the best way to store it should be a digital file. Are you saying we should write it down in steel?
Can you post an photo of what seedhammer looks like?
Oh shit! 
I sometimes take a little time but eventually I get there :) Thanks for showing me this.
But I wonder if I can achieve the same thing by printing a QR code on paper, laminating it and storing it inside a fire and waterproof container?
Its probably cheaper....
