No hammer, no punches — just write.\u003c\/p\u003e\n\n\u003ch3\u003eWhy tungsten carbide\u003c\/h3\u003e\n\u003cp\u003eTungsten carbide is hard enough to cut into stainless steel and keep its point. You can engrave a full seed phrase, and then another, without the tip going blunt.\u003c\/p\u003e\n\n\u003ch3\u003eStamping or engraving?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eEngraving with the CryptoSafe Pen\u003c\/b\u003e is quiet, needs no hammer, and lets you write freehand. Marks are shallower than stamped ones.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eStamping\u003c\/b\u003e with the CryptoSafe Stamp and Hammer gives deeper, more uniform characters, but needs both tools and a firm surface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBoth outlast paper by a wide margin. The CryptoSafe Pen is the simpler option if you want one tool and no noise.\u003c\/p\u003e\n\n\u003ch3\u003eWorks with\u003c\/h3\u003e\n\u003cp\u003eThe CryptoSafe Lite steel plate, and any hardware wallet whose recovery phrase you want backed up in steel — Ledger Nano S Plus and Nano X, Trezor, Tangem, SafePal, D'CENT, CoolWallet and KeepKey among them. Tangem is seedless by default, so this applies if you have chosen to create or import a seed phrase.\u003c\/p\u003e\n\n\u003ch3\u003eWhy engrave rather than write\u003c\/h3\u003e\n\u003cp\u003eInk fades, paper burns, and in Thailand termites eat it. An engraved steel plate keeps your words readable through heat, water, humidity and time.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eDoes it need a hammer?\u003c\/b\u003e\u003cbr\u003eNo. You engrave by hand, like writing with a pen.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIs it as durable as stamping?\u003c\/b\u003e\u003cbr\u003eThe plate is equally durable. Engraved marks are shallower than stamped ones, so write firmly and go over each letter more than once if you want a deeper line.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I use it on the CryptoSafe Pro or Capsule?\u003c\/b\u003e\u003cbr\u003eThose use pre-made letter tiles and need no marking tool. The CryptoSafe Pen is for the CryptoSafe Lite plate.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003eCryptoSafe products are sold \u003cb\u003ewithout warranty\u003c\/b\u003e and cannot be returned or exchanged.
