The Bitcoin whitepaper etched into stainless steel!
The Bitcoin Whitepaper was published in 2008 by Satoshi Nakamoto, and it changed the course of history. Now you can display those 8 pages on one large piece of stainless steel. The Bitcoin whitepaper comes polished for legibility. The lettering of the Bitcoin whitepaper is etched into the surface to ensure it will stand the test of time.
Whats New: We have made some minor adjustments to accommodate a larger 15"x 21" size!
Material: 304 Stainless Steel

How It Works
First four letters,
punched into steel.
Each BIP-39 word is uniquely identified by its first 4 letters. Each word gets its own column. Each letter tells you which row (A–Z) to go to. Mark the quadrants clockwise: 1st letter = top, 2nd = right, 3rd = bottom, 4th = left.

Bitcoin Backup Questions, Answered
Everything you stamp into steel matters. Here are the most important things to know before backing up your Bitcoin seed phrase.
What should I put on a Punchplate? +
Only your wallet recovery words, exactly as generated by your wallet.
Do I need a 12-word or 24-word Punchplate? +
Use the format your wallet gave you. If your wallet generated 12 words, use a 12-word plate. If it generated 24, use a 24-word plate.
What about a passphrase? +
If you use a BIP39 passphrase, remember that your seed words alone are not enough. You need a separate secure plan for preserving that passphrase too.
Should I make more than one backup? +
Yes. Many Bitcoin holders keep at least two backups in separate secure locations in case of theft, fire, flood, or loss.
Can I test my backup? +
Yes. The safest approach is to verify that your recovery words can restore the wallet before moving bitcoin or relying on the backup long term.
What if I punch the wrong spot or letter? +
No stress — Punchplate was designed for this. If you hit the wrong spot, simply punch the exact same spot 3–4 times. This creates a dense cluster of dots that is impossible to confuse with a real punch.
Every valid character on the finished plate is always a single clean punch. Canceled marks stand out clearly as overlapping groups, so you (or anyone reading it later) instantly knows to ignore them and move to the next valid letter.
