Not sure, so I asked AI:

Brushed stainless steel (like the keys) offers a textured surface that eliminates the need for additional sanding. However, thorough cleaning with isopropyl alcohol or a degreaser is essential to remove oils, dirt, and contaminants. For a strong, durable bond, use a two-part epoxy or a polyurethane adhesive formulated for metal.

However, that could be messier than with soldering. Because you can't know where the glue will go when you press the keys together. It could come over the letters, and when you remove that glue (not sure how to do that), it may make the letters unreadable.

Sounds like a hassle. To make the set tamper-proof, better to put the device in a container, like a safe deposit box.

Yeah I was thinking that it could be prized open with a blade and screw driver, and broken in such a way that means accessing it is destroying it.

I feel like someone could also steel this and replace it with an empty key set, if they could forge the label on the tamper proof tag.

Maybe I'm paranoid, but only the paranoid survive as they say.

Multi-sig is one solution, but I don't believe it's appropriate for most people because it's easy to fuck up.

Also, I suggest adding another piece of metal for accompanying details, such as derivation paths or whatever. This solution should be accessible to non-Bitcoiners for inheritance reasons, and basic things like not being aware of derivation paths can trip people up when they've never recovered a wallet before.

That goes further than what I had in mind. My first thought is: that would probably weaken the whole backup. But I find the idea interesting.

Thanks for the suggestion.

There's an extra blank key, but not sure if it could fit the derivation path.

Also, to save on transport costs, the letter punches I have in stock don't have letters. But you can easily find one in a local store.
