Review: Rock Solid key storage. - This is great way to protect your seed phrase (the generated sequence of words that can be used to recover your crypto wallet though if you're looking at this listing, you probably already know that) and way better than paper. Paper burns, paper gets wet and falls apart, paper can be torn and lost, etc. Well I can't test how fire resistant this is, but it seems very sturdy and would definitely survive most hazards. Assuming it's actually quality steel it shouldn't rust easily or melt in a typical house fire. $50 is pretty pricey for 4 small sheets of stainless steel and some stamped metal letter cards, but it's worth it if you're looking for a simple & secure way to store your crypto. There are cheaper home-made options that use washers and metal stamping tools, etc.. to build your own fireproof/waterproof storage for way less, but they're not as nice looking as this and require a lot more work. It swivels closed and you can put a small lock through to keep it secure. It comes with sheets of letters punched into metal cards that you set into this card after unscrewing the top layer, which prevents them from falling out or getting mixed up. It's not the whole word every time, but the first 4 letters are enough because there are intentionally no similar words in the seed phrases that could get mixed up like helicopter and helix for example. Both sides of the card can store 12 words, so you can do one wallet with a 24 word seed, or two wallets with 12 word seeds. There are a few issues that you should still keep in mind though, not with this hardware itself, but just in the concept of secure storage in general. 1: If it exists in physical form you can secure it with a lock or put it in a safe, but as long as someone knows it exists, given enough time, they can break into anything eventually. For example, this device seems great, but a determined thief can cut through your lock shackle, pick the lock or maybe just break the hinge, etc.. It's pretty thick and hefty, but that really only means it might slow someone down or stop the people that are afraid you'll find out they messed with it. 2: Because we know any physical security can be defeated your best line of defense against other humans is security through obscurity (it's unknown or hidden). Don't tell anyone about it that you don't 100% trust and hide it somewhere nobody could stumble onto it by chance or search. The ultimate security is memorization, where your seed phrase literally doesn't exist in the physical world, and is only known to you in your own head. However, humans aren't perfect, and it's possible for people to get injured or otherwise forget things so, secure storage like this is the next best option.
Review: Peace of mind for your crypto phrase - The Prokey ColdSteel backup has a heavy feel to it. The top and bottom plates are thick and very stiff. This is important because bending could create a gap between the plates and the frame, which could allow the recovery word letters to get scrambled. After I loaded my phrase, I gave it as vigorous a shake test as I could, then dropped the ColdSteel from 8’ (onto carpet). The words all remained intact. I like that the letters are engraved, rather than painted and the letter plates had a protective backing that kept them from scratching adjacent letter plates during shipping. The reason for 4 stars and not 5 is that I used up all p’s and d’s, without one to spare, despite the fact the letters are interchangeable by flipping. Several of the letters are interchangeable by flipping them upside down: b=q, d=p, and n=u. I would have been very disappointed if I had to scratch my own letter onto the backside of a spare letter had I needed one more d or p letter. I do recommend the Prokey ColdSteel for phrase backup.
