The KeyTag measures just 36 × 33.5 × 3 mm and weighs 14 g—roughly the size of an SD card. Hide it in a wallet, toolbox, or any nook you like, yet retrieve it in seconds. Machined from TC4 / Ti‑6Al‑4V (Grade‑5 Titanium), it shrugs off heat up to 1 668 °C and offers even greater corrosion resistance than 316 stainless steel. Fire, water, and rust don’t stand a chance.
Highlights
Tiny & discreet — slips anywhere but is easy to locate when needed.
Grade‑5 Titanium — aerospace‑level alloy: unmatched strength, heat, and chemical resistance.
Auto‑Center‑Punch included — spring‑loaded mechanism fires with a light press; precise, effortless, no slip.
Dot‑matrix layout — secures 24 BIP‑39 words plus an optional passphrase with near‑zero typo risk.
Hard base = effortless stamping
Accurate marking demands a solid surface. Soft wood or plastic absorbs impact and makes stamping a chore. Use our 10 × 10 × 1.5 cm heavy‑steel stamping block —it absorbs kickback and protects your table.
