Make easy backups in stainless steel
The Seed Jig is a tool that allows you to neatly stamp your bitcoin seed phrase into stainless steel washers.
Why washers? Why Stainless Steel?
Washers are readily available almost anywhere and are inexpensive. The handy central hole means a stack of ’em can be stored on a bolt and secured tightly with a locknut. Thus, you can store a 24 word seed phrase in a compact, inconspicuous package that is highly resistant to damage by fire, water, impact and atmospheric corrosion (that’s the stainless steel part!). Once you have a SeedJig you can create many backups of many wallets for very little extra cost.
In summary: Iron + Chromium + Nickel in an O shape = the perfect medium to store your most precious data.
