Description
Blockmit Crypto Seed Phrase Jig
This specialized Blockmit stamping jig enables cryptocurrency enthusiasts to create durable, fire-resistant backups of BIP39 seed phrases on M8 metal washers. The tool holds washers securely while you use 3mm letter and number stamps to permanently record wallet recovery words on stainless steel, putting physical backup creation in your hands.
Precision Security Tool from Canada
Manufactured in our Quebec facility using PLA selected for dimensional accuracy and durability. The jig’s precise alignment ensures consistent letter placement across all washers, creating professional-looking backup sets.

Designed specifically for M8 washers and 3mm stamp sets (sold separately), this jig ensures proper fitment and alignment. The standardized sizing means washers are readily available at hardware stores, making backup creation accessible to any cryptocurrency holder committed to proper security practices.
