UPDATE on SEEDPHRASE backup project.

Purchased a rotary tool to engrave stainless steel, it allows me to design, polish, personalize and customize my seedphrase keys, long-term at home, with privacy, without intermediaries, digital footprints or hazardous processes - remember to use a magnifying glass, clamp, goggles and mask - upgrading your keys is a fun, creative and intelligent process, you can even find creative ways to spray paint or anodize. Stainless steel can whitstand fire, corrosion, earthquakes, floods and ice.

Keep your keys SAFU!
