Iām building a metal seed backup. What would make it worth choosing over DIY? Hi everyone. Iām the founder of PENGER, a project making metal backups for Bitcoin recovery phrases. This is my own commercial product, and I want to be transparent about that. Iām posting to get feedback on the design and the thinking behind it, rather than turn this into a sales thread. Iām not claiming to have invented metal seed storage or a new security standard. My question is whether a more carefully finished product, with clear instructions and thoughtful support, adds something worthwhile to an already familiar idea. What it actually is The design is a solid, 2.5 mm-thick plate, with stainless steel and titanium versions and an optional leather sleeve. There is space for up to 24 BIP39 words, which the owner records using a center punch rather than assembling individual letter tiles.
