Why 304 stainless steel
A stable material for the information you cannot replace.
304 stainless steel is widely used where strength, cleanability, and corrosion resistance matter. Its chromium-rich surface forms a protective layer that helps the metal resist everyday oxidation and moisture.
For a recovery phrase, that means a solid surface that does not rely on ink, batteries, software, or an online provider to remain readable.
- Maintains its form. A rigid plate is less vulnerable to tearing, creasing, or accidental disposal than paper.
- Accepts a physical engraving. Your words are cut into the surface rather than printed on top of it.
- Easy to inspect. You can verify legibility directly, without a device or proprietary reader.
Designed for long-term clarity
Different backups fail in different ways.
The goal is not to promise an indestructible object. It is to remove fragile dependencies and give your recovery words a more resilient physical home.
Durability is a system
The material is only one part of a dependable backup.
Practice first
Use the included practice plate to learn the engraver and find a clear, repeatable technique.
Engrave and verify
Make each word legible, preserve its correct order, and compare the finished plate carefully with the original phrase.
Store deliberately
Keep the completed plate private, clean, and dry in a secure location only you or a trusted recovery plan can access.
Plain-language material note: 304 stainless steel is corrosion resistant, not corrosion proof. No backup is indestructible. Exposure conditions, engraving depth, and storage choices all affect long-term performance.
Material questions
What to know before you store it.
Why use 304-grade stainless steel?
304 stainless steel offers a practical balance of strength, corrosion resistance, availability, and engravability. It creates a stable physical surface for information that should remain offline.
Will 304 stainless steel rust?
304 stainless steel is corrosion resistant, not corrosion proof. Keep the plate clean and dry, and avoid prolonged exposure to saltwater, harsh chemicals, or other aggressive environments.
Is the plate fireproof or waterproof?
Steel does not burn or absorb water like paper, but we avoid absolute durability claims. Real-world performance depends on the intensity and length of exposure, engraving depth, and storage conditions. No backup is indestructible.
What helps an engraving remain legible?
Practice before using the final plate, engrave each character clearly, and inspect every word and its order when finished. A mark that is physically cut into the surface does not depend on ink remaining intact.
How should I store the finished plate?
Store it privately in a secure, clean, dry location. Treat it as the key to your wallet: anyone who can read the complete recovery phrase may be able to access the funds it controls.
