A samourai in combat used katana made from precious steel (tamahagane). This type of steel was created from a traditional smelting process that resulted in unparalleled sharpness and strength of the sword. Modern martial artists still use a variety of katana.

These days Bitcoin hodlers don’t use swords but rather cryptographic tools to fight the omnipresent surveillance state. Samourai Wallet is a good example of such a tool. Focused on privacy and ease of use it makes day-to-day transactions in Bitcoin possible completely bypassing the current financial system.

That’s why we teamed up with folks at Samourai Wallet to create a Samourai themed edition of Coldbit Steel.

Why do I need Coldbit Steel – Samourai Edition ?

Samourai Wallet uses BIP39 mnemonic seed + obligatory passphrase as a backup mechanism.

Coldbit Steel lets you stamp this seed on a plate made from stainless steel and your passphrase on a stainless hex rod.

This way even if you lose your mobile phone with Samourai Wallet on it you have a very secure and durable backup of your wallet that you use to recover the wallet.

I can back up the seed on a piece of paper. Is it a good idea ?

Paper will not survive flood, house fire, car accidents and other catastrophic scenarios. Stainless steel will. Besides samourai use steel, not paper.

What’s included in the package:

  • 1x Coldbit Steel – Samourai Edition
  • 1x Coldbit Passphrase
  • 1x testing plate/support
  • metal box

What’s not included:

  • A katana. The best way to obtain a katana is to find a sword-smith who can forge it. The second best way is to learn to make it yourself.
