NGRAVE GRAPHENE
A two-plate 316 stainless steel backup where you punch characters through a perforated upper plate into the lower one, so neither plate alone reveals the phrase. NGRAVE states it resists fire to 1375°C plus water, corrosion and shocks, and can reissue a lost upper plate via a recovery code.
