I don’t know why everyone is suggesting complicated means to destroy the steel plate. Acid is expensive and hard to come by and how will you melt it at 3000C in your home?
All you need to do is take a drill and make a few holes in it and you are done. If the drill breaks it means you got a cheap bit. Buy one of those $5 bits and it will drill thru steel like butter pretty much.
You also don’t need to drill all the way, just enough to destroy what is written on the main surface.
This pretty much. Even easier if you stamped the letters yourself, just stamp more letters over each of them to make it unreadable.
Melting is too complicated. Though I would argue it is one of the best methods if you do not want some body to find out you own Bitcoin. This or you drill it and drive 50 miles away from home and throw it into a bin in the middle of a forest, then go back home.
This is because I am more afraid of getting rid of the plate itself than about destroying the Seed so it becomes unreadable. If no body knows I hold Bitcoin, I would not want them to see the plate. Even more so if the plate has been drilled. It could spark some thoughts about your holdings. Such as, who would put such effort into drilling the plate, unless they hold a lot of Bitcoin?
If its stainless steel you ideally need Cobalt drill bits otherwise with hardened steel
bits it will become very tedious.
I first thought of just stamping more letters over the words but that can be time consuming too.
The quickest way is to just grind off the letters, stick the plate in a vice and grind away,
all done in about 10 minutes.
