Engraved onto something like titanium would be better than a fireproof safe - they're only safe for X amount of time (I want to take a stab in the dark and say about 90 minutes?). This is how I have backed up some (since retired) crypto seed phrases in the past.

Where do you keep the titanium plate? I'd be more worried about losing it due to a natural disaster than merely having it destroyed beyond readability in a natural disaster.

Sure, sounds perfect. Let me send some crypto person that has invested in a home stamping kit the secret to my crypto wallet. At least they won't know what it's for to be able to hijack my wallet. phew. had me nervous that committing the cardinal sin of sharing my secret with someone I don't know isn't going to come back to haunt me.

You assemble it at home? You do not send anyone your secrets.

Also, the idea is simple enough you could DIY your own version with stuff from any hardware store.
