Installation Guide.
BIP 39 specifies a word list of words, and of those words, the first four letters are all unique. On many wallets, if you enter the first four characters, the rest is auto-filled for you. Some words in the list only have three characters, like ADD. Not every wallet uses the BIP 39 standard. Trezor uses a variant called SLIP 39 and Electrum uses its own scheme, but all hew to the same BIP 39 conventions even if they use different wordlists.
Both support seeds of up to 24 words, each four characters long. The chief difference between the two is that the base model is held together with only three screws while the Plus uses 13 screws. The Keystone Tablet Plus also has an individual well for each letter tile, reducing the chance that the letters will move if the steel warps.
Putting things together was simple but tedious. You swivel the two plates open and the inside of each half has wells for 12 seed words, each numbered from Carefully remove the screws from one plate a screwdriver is included , set them aside, and slide away the top section to reveal the letter wells.
There are also a few extra screws included in case you lose one. Once the letter wells are exposed, break off letter tiles from the three steel sheets and insert them into each well. Take care when breaking the tiles free to not twist the tile itself, as that will warp it and prevent the case from sliding shut.
Thankfully, each letter has multiple spares so you should have plenty. If a word has only three letters, break off a spare letter and insert it backward in the fourth well of the row, so the blank side faces you. When sliding the two halves of the plate back together, you have to be very careful to not knock any of the tiles out of their wells. Before replacing the screws, review each word closely.
The two halves of a plate will not separate if even one screw is still in place, much less the 13 that are there. I find it to be very sturdy. I guess you might have a problem if the hinge that holds the two sides together failed, but I think that would be pretty easy to fix.
The words would be slightly easier for an interloper to see, but the tiles would still be securely in place. Both Keystone tablets have a hole that goes through both plates where you can attach a lock for extra security. That would also serve to hold the unit together if the hinge failed. Interesting products. But, if I understand the parameters of the problem correctly, you could just use an easy etcher to etch your passphrase onto a piece of scrap metal, for half the money and less hassle slightly more noise.
Note that it comes with a set of letter templates. I should have practiced on some scrap first. For reference — several sources suggest that house fires generate heat between F C and F or F C — C e. So ideally, this steel would be able to withstand most types of common house fires which ideally, would never happen, knock on wood. Good to know that by itself it should be able to withstand a house fire. Most people will keep something this important in some sort of safe which hopefully will add additional layers of fire resistance.
You are reporting the comment " "" by on. There are several ways to achieve this: Scratch the seed phrase in metal with an awl, which requires a steady hand, though there are kits that include templates to make it easier Engrave it with a Dremel or other tool, which requires an even-steadier hand Use a letter punch set and a hammer to punch the letters into metal, which is loud and time-consuming Use a laser engraving machine, which is probably the best method, but requires expensive equipment you may not have other uses for The Keystone Tablet Plus formerly known as the Cobo Tablet Plus is a pair of metal cards that lets you encase metal letter tiles, much like a Scrabble board.
