- Density: 4.5 g/cm³ (56% lighter than steel with equal strength)
- Hardness: HRC 36-41 (scratch/drill-resistant surface)
- Corrosion Resistance: Immune to rust, acids, and seawater
- FREE BONUS: Tungsten Steel Stylus Punch Needle (HRC 90+ Hardness) & Protective Case
How to use:Use the punch needle to mark specific positions on the metal plate to record the BIP39 mnemonic serial number (ranging from 0 to 2047). For example, the mnemonic "happy" corresponds to serial number 839in the BIP39 standard table. As shown in the figure below, the value is calculated as:1 (2⁰) + 2 (2¹) + 4 (2²) + 64 (2⁶) + 256 (2⁸) + 512 (2⁹) = 839. Mark these binary positions with the punch needle on the metal plate.
You can enhance protection by punching the offset positions by shifting the position, such as moving it +1 to the right (e.g., True Position 0 → Marked Position 1)
Recovery Process: Sum the binary values of all marked positions on the plate. Use the total value (0-2047) to find the exact mnemonic word in the official BIP39 wordlist.
