isn't that dumb,  because the manufacturer knows your private key?

 @kaia hey! That's called "backup" 
 @kaia seems to dangerous to me. Usually with those metal 'wallets' you engrave it yourself, that makes more sense. 
 @kaia no no, they are definitely trustworthy, especially in a rock solid industry like cryptocurrencies 
 @kaia Do they? I expect anything most stupid from that "industry", but they could just print your pubkey on it and rely on you uploading your secrets yourself to the card when you receive it.
