Brainwallet with Shamir's Secret Sharing

[Wary]

Is there such thing? To break a passphrase to several parts.

The closest thing I've found is  http://weissjeffm.github.io/bitaddress.org/bitaddress.org.html on tab "Split Wallet".
But there is no field to enter the passphrase to split.  
Anybody knows a SSS password-splitting java script?

Have you looked at Armory?

From  the changelog (Version: 0.88-beta (18 Apr, 2013)):

Fragmented Backup Scripts (Expert Only). Two new scripts added to “extras” directory: “frag_wallet.py” and “unfrag_wallet.py”. These scripts can be used to split your wallet into pieces/fragments using Shamir’s Secret Sharing. This is only available from the command line, but will be integrated into the application itself in the next release. The new interface will include restoring fragmented backups created with these scripts.

There is currently a more recent version in testing, which might have better usability. I haven't tried it.

Edit: Ah, you are looking for a brain wallet. Doubt Armory does that. Maybe it is useful anyway.

Brainwallets are generally a bad idea if you want to hang on to your coins.

You might enjoy this though.
