We use the ColdTi.com Titanium plate for our crypto seed storage. Instead of buying and using a punch set, we purchased a Dremel Electric Engraver model 290-01 120-Volt model. It’s much easier and you will always have other things you can engrave. Also, instead of etching our seed words onto the plate, for extra security we use the corresponding number from the BIP39 word list. Which you can find at Github: BIP39 Wordlist in different languages or one from kryptodots that is easier to print.
Why you should use a metal plate wallet to store your recovery seed phrase:
1. Offline: safe from hardware failure, no third-party trust required, safe from online hackers
2. Rugged and Durable: fireproof, waterproof, rust and corrosion resistant (for stainless steel and titanium plates)
3. Transferable: can be given to your loved ones or heirs, your coins are always recoverable with the seed key
