I dig buidl! SLIP-39 is super cool and useful, would love to see it in more places.

I wrote a shamir secret sharing scheme to back up a BIP-39 in the buidl library.

You can have k-of-n and each share has the same number of words as the combined one. So for example if you have a 24-word seed, you can split to 3 24-word shamir shares, of which you need 2 to construct the original 24 word seed.

How to split your BIP-39 mnemonic into a 2 of 3, using simple math you can do in your head.
