Hi mate, cor coldstorage do you reset the hardware wallet to remove the keys and keep just the back up?
Nah, if i want to have multiple wallets based off of a single hardware wallet I will often do it via multisig (Nunchuk makes this dirt simple) and adding a separate second key for it, or I use a 25th word to generate a new wallet. But I haven't done that in quite some time however. I mostly use various multisig setups with differing levels of security and ease of access.
