When it comes to seed phrase backups, you'll likely be tempted to purchase the latest expensive seed phrase stamping technologies. I would challenge you to instead invest in your own stamping kit using washers. It'll save you loads of money.
Here's the supplies list:
- Blockmit Washer Jig (you can print this yourself if you have a 3D printer! Look it up on thingiverse)
- Steel metal stamping tool set (1/8") 3mm (Amazon)
- Steel bench block (Amazon)
- Pill bottle survival containers (Amazon)
- hammer
- Stainless steel 316 Washers, 8mm x 24mm (Bolt Depot is a good resource)
- Metric hex bolts, Stainless steel 316, 8mm x 1.25mm x 60mm (Bolt Depot)
- Metric hex nylon insert lock nuts, Stainless steel 316, 8mm x 1.25mm (Bolt Depot)
You can then follow the same strategy to stamp your own recovery seed words into the washers, load them on to the hex bolt, and secure with the lock not. The entire assembly then fits very nicely into one of these pill bottle survival containers.
That, or you can overpay over and over again for the latest in seed phrase stamping technologies as marketed by your fav youtube sensation.
Here's a nice video if none of this is making sense:
