OneKey KeyTag Crypto Seed Storage Titanium Backup Plate (2pcs with Punch Tool) 24-Word BIP39 Recovery Phrase Metal Wallet Compatible with Ledger Trezor Safepal KeepKey Cold Storage

This is my favorite seed backup option. Compact and inconspicuous as much as it can be. I have a couple cryptosteels plates with slide in letters. They are overpriced for what they are and feel kind of cheap. Durability of the onekey is top notch being titanium. The 2X24 word seed + 25th word is great. Get these backup plates.

From the photos I thought the tiles were single-sided & 1 had words 1-12 & the other had 13-24. However, when it arrived I was pleasantly surprised that they are double-sided so you can do 2x24 word phrases (or 2 copies of 2.)

It’s a very clever way to store your key phrase or any phrase password for that matter.

From the encrypted method to record a seed phrase, to the tiny, inconspicuous seed plate, and even the beautiful packaging, everything is top of the line---until you go to punch the plate with the completely useless punch tool provided. No mater how much force I applied, I literally could not get the included punch to make a single hole in the plate. I had to purchase a new punch that worked. For the price, the included punch should work flawlessly. For that reason I subtracted two stars. The new punch I purchased worked with ease, required minimal force, and caused me no pain while using the tool. For those willing to accept that fact that they too may have to purchase a punch that works, I recommend this seed storage system.

At first when you're reading the instructions, it may seem a bit complicated or overwhelming. But once you go back and reread it a couple times you'll start to understand the decoding process and how it all works. As far as the quality and the workmanship of the tags and punch tool, everything was very high quality. The punch tool actually has a spring mechanism inside of it to give it some shock absorption before it punches the tag hole. What's great about the whole thing is, once you have punched your tags with your coding, the punch tool itself can be used in the future for other projects and good to keep in your toolbox. Everything about this product in the company are first class. Even the boxing was very high-end like you would see with expensive video cards. It seemed a bit pricey for what you get, but maybe that's because of the titanium.

Not much to say. A simple product that does exactly what it is supposed to. Resistant to pretty much anything you might encounter...fire, water, earthquake, alien invasion, etc.

Excellent way to keep your seed secret.

Perfecto, para mi es el mejor sistema de backup

Die Platten haben eine ordentliche Qualität und sind optisch ansprechend gefertigt. Das beiligende Werkzeug ist allerdings von sehr minderwertiger Qualität. Nach etwa 20 Stanzungen kamen die ersten Fehlfunktionen. Diese wurden dann immer häufiger und nach 50 Stanzungen hatte ich 80% Aussetzer. Ich habe dann mit einem einfachen Körner und einem Hammer weitergearbeitet. Außerdem verstehe ich nicht, warum nicht mit der BIP 39 Liste gearbeitet wird, die mit Wort "0" beginnt, dann ließe sich eine Spalte einsparen. (Die Spalte "2048" braucht man dann nicht.) Insgesamt ist die Ware für die gebotene Leistung zu teuer. Für 30-40 EUR wäre es OK. Allerdings war alles sehr hochwertig in einzelne Kartons verpackt und die Lieferung erfolgte sehr schnell.

Ottimo metodo per poter scrivere in modo abbastanza discreto la propria seed phrase...sui materiali niente da dire, sono spaziali!🚀 Molto comodo il punteruolo incluso ed il libretto con le somme già calcolate per ogni parola della Wordlist BIP39. La placchetta consente anche di poter segnarsi 2 parole aggiuntive, ovvero le passphrase. Un plus è che questa placchetta potrebbe essere anche cifrata secondo un proprio metodo personale di cifratura (che io non ho usato perché sfido chiunque a ricordarsi tra anni e anni il metodo di cifratura senza scriverlo da nessuna parte, il che farebbe calare drasticamente il livello di sicurezza) Ciò che conta, è come poi viene custodito e soprattutto dove :) Consiglio l'acquisto per tutti possessori di wallet, ma in particolare per chi vuole diffidare da hard wallet come ledger o simili, e creare il proprio wallet tramite il metodo dell'entropia (con i dadi, consiglio il video di TheCryptoGateway!) , in modo che la seed phrase non passi per nessun tipo di dispositivo.

It’s a great nicely packed product. Could be used as a desired present or a birthday gift. Punching holes for a 24-word seed phrase might be a bit tedious though :)

金属にパンチするので信頼性は非常に高いです。仮に火災になっても回復フレーズは読みだせます。 単語と数字は付属のブックレットに対応表があります。この単語と数字の関連は標準的な物かは分からないですが、github の bip39-dotmap で確認できます。 本製品はOne key 専用だと思われますが、使っているシステムの回復キーの単語が bip39-dotmap に含まれ、50文字以内であれば流用可能だと考えます。 本製品は金属の塊なので、一般の住宅の火災程度では記載されている内容が無くなる可能性は低いと考えます。 耐火金庫に入れておけば万全だと思われます。 火災にならなくても、プリントアウトした紙より信頼性は高いです。 欠点としては二進数に慣れていないと解読や打ち込みが難しい点です。そのため、説明なしにこれを見て使い方が分かる人以外は手を出すことはお勧めできません。 パンチ（ポンチ）するときは激しい音が出ます。集合住宅や他の家族が住んでいる家では迷惑になる可能性がありますので時間と場所を考慮してください。 理想は屋外や工場のような場所ですが、一度ミスをするとやり直しが出来ないので、他の人が絶対に来ない集中できる場所を選んでください。 付属のワンタッチセンターポンチは動作が不安定です。何度かポンチ出来ずに空振りすることがあります。もし、手持ちのポンチがあればそちらを使うことをお勧めします。 パンチをする部分は微妙にへこんでいますので、ポンチの先端を滑らすようにそのへこみに入れてから、打刻してください。 打刻する場合は力が必要です。安定した作業台の上で行ってください。手に持ったり、足などに置いて打刻は不安定でミスや怪我が発生する恐れがあります。
