I respect DarthCoin, but reject dabbling in Shamir Secrets, using substitution cyphers, custom derivation paths, multisig, etc. You become your own worst enemy instead of a potential attacker.

Choice quote from that page:
...many attempts at SSS [Shamir Secret Sharing] have been so weak a child's speak-n-spell could crack them. Like the one-time-pad and most other cryptosystems, the security of SSS is fairly brittle.
