I want to be able to construct the orginal back from only two parts, so if i am able to lose one or even to parts, i can construct it back anyway. I also want the extra security that if someone only find one they cant use it. If the hiding spot i was thinking of was a lot worse than i thougt and some people find it, i dont want them to be able to get any information from that and get acess to my fund. I know I need to construct them back one time, but i can do that mannualy, so the only thing I need to trust with my hole private key is ledger. But I think that is safe enough for me.
