Hey #nostr community I would like to watch a video channel of how other #Bitcoin users BUILD their seedphrase backup keys. I recently created a seedphrase and backed up my word sequences, nsec and passwords with a SAFU NINJA backup. Some of the products and techniques I see online are very risky against fires or floods.

Stamped stainless steel washers, once stamped (not carved or laser engraved) keep a lifetime imprint on metal which can withstand a 300°C degree fire or a -300°C drop in temperature, corrosion or vibration. Stamping on Stainless Steel over a hard base is the secret to keeping your keys safe, has anyone else developed home techniques to stamp stainless steel?
