well then that's going to be a long process.
The Kraken attack took only 15 minutes to extract the seed phrase from Trezor devices, and the Ledger attack took around 5 minutes. That is not a long process by any means. Home safes can vary widely in quality, and poor ones can be cracked open in under a couple of minutes. Worst case scenario, an attacker could open your safe and perform this attack in 15-20 minutes. Even if your safe requires hours to crack, if you are at work for 8 hours a day that is more than enough time.
If you are planning to use a Trezor device, then you should follow the instructions here (
https://wiki.trezor.io/Passphrase) to set up a long and complex passphrase, to mitigate against the physical vulnerability of the device.
