No, not a single plate.
Yes, it's quite similar to cryptosteel, but a lot nicer and for slightly different use. It is bigger because it can store your trezor or ledger, which is the main added feature. So the best way to use it is to bury it under the ground in your backyard and wait for the apocalypse to come. Then you dig it out, take out the trezor, put seed in it and you are good to go surviving.
Or you can just put it on your table as it is a really nice piece of metal.

Thank you for your replies.
We are working on a metal case for backup seed and hardware wallet. We want to laser engrave the seed on small plates from stainless steel, but also make to it 100% secure. Out attempt is not to make our customers trust us but instead, make it that there is no need to trust us. They are protected by math.
I'm absolutely certain that our model is safe. Every customer will need to give us 60 words. That gives us 2.2e40 variations. I just need to put some easily understandable numbers behind it.
That's way figuring out how much variations can some known processor try out in a second would give me pretty much all I need.

Hello, I'm trying to figure out how much time would it take to guess a backup seed of a wallet if I had all 12 or 24 but they were shuffled.
I know how many combinations that is. 12! and 24! are fairly simple answers.
What I can't figure out is how much time would it actually take to some CPU using a specially designed script? Just creating all possible variables and then trying them out.
How many processor operations does it take to set up first 24 words and then run it through some wallet to test it out?
How many of this variables can some intel core i7 try out in a second?
Can anyone help me out? I wasn't able to find my answers in different parts of the internet. Most of the talk is about brute-force if you just know it can be any of 2048 words.
